The Journal follows the AMA Manual of Style for manuscript submitted to biomedical journals. Set your document as A4 (International Standard: ISO 216) paper, use double-line spacing, Arial font size 12, do not justify the right margin, add line numbers and page numbers. Save your manuscript as a Word document (.doc, .docx, or previous; Open Office or RTF formats).
Structure your manuscript file as follows: Title page, Manuscript Text, Acknowledgments, Figure legends, References, Tables.
The first page (title page) of your manuscript file must include the following information:
Divide the text as indicated for each content type. Use commas (,) to separate thousands and full stop (.) for decimals (e.g. 12,354.55). Include tables in the manuscript file, after the references. Number all figures (graphs, charts, photographs, and illustrations) in the order of their citation in the text. Figures must be submitted as separate files and not embedded in the Word document.
If relevant to your study, include a statistical methods section, describing adequately the methods used to allow reproduction by independent analysis of the dataset. Include a statement on how the data presented were selected including prospective sample size calculations, the reasons for including/excluding subjects or data points, and what steps the authors have taken, if any, to exclude intentional or unintentional bias in recruitment, measurement, data retention, analysis, reporting and comment. Keep discussion to a minimum in this section of the manuscript.
Units of Measure
Laboratory values are expressed using conventional units of measure, with relevant Système International (SI) conversion factors expressed secondarily (in parentheses) only at first mention. Articles that contain numerous conversion factors may list them together in a paragraph at the end of the Methods section. In tables and figures, a conversion factor to SI units should be provided in a footnote or legend. The metric system is preferred for the expression of length, area, mass, and volume. For more details, see the Units of Measure conversion table on the AMA Manual of Style website.
Names of drugs, devices, and other products
Use non-proprietary names of drugs, devices, and other products, unless the specific trade name of a drug is essential to the discussion.
Cancer classification scheme
Authors are encouraged to use the American Joint Commission on Cancer TNM Classification scheme (see AJCC Cancer Staging Manual, 7th Edition, Springer, New York).
Use only standard abbreviations: the full term for which an abbreviation stands for should precede its first use in the text. Do not use abbreviations in the title. All abbreviations must be spelled out when they are used for the first time in the abstract and again when they are used for the first time in the text.
List in this section
You may include in this section each author contribution to the manuscript (see Editorial policies for authors)
Written permission must be obtained to include the names of all individuals included in the Acknowledgments section. If the manuscript has been presented at a meeting, please indicate in this section its name, location, and date.
Data Availability Statements (DASs). Provide a statement about where data supporting the results reported in a published article can be found, including, where applicable, unique identifiers linking to publicly archived datasets analyzed or generated during the study.
Figure legends and legends for supplementary material
At the end of the manuscript, include a short title and a legend for each figure. When symbols, arrows, numbers, or letters are used to identify parts of the figures, identify and explain each one clearly in the legend.
For photomicrographs, include the type of specimen, original magnification or a scale bar, and stain in the legend. For gross pathology specimens, label any rulers with unit of measure. Digitally enhanced images (CT/MRI, blots, photographs, photomicrographs, ultrasound images, x-ray films, etc.) must be clearly identified in the figure legends as digitally processed images. References used within figure legends should be included in the reference list and numbered in consecutive order according to the figure citation in the text.
Any figure that has been published elsewhere should have an acknowledgment to the original source; a copy of the permission to publish the figure, signed by the copyright holder, must accompany the submission.
Authors are responsible for the accuracy and completeness of their references and for correct text citation. Personal communications, unpublished data, abstracts, and oral or poster presentations should be limited and incorporated in parentheses within the text without a reference number. A signed permission should be included from each individual identified in a personal communication or as a source for unpublished data, as well as the date of communication.
References must be double line spaced and numbered consecutively in order of appearance within the text, using the automated numbering tool of Word.
Identify references in text, tables, and legends in Arabic numerals in parentheses, i.e., (7).
List all authors when six or fewer; when seven or more, list only the first three and add et al.
References used within tables or figure legends should be included in the reference list and numbered in consecutive order according to the table/figure citation in the text.
Journals’ names should be abbreviated according to Index Medicus/Medline. If there is any doubt about abbreviation of a journal name, it should be spelled out completely.
Any references to studies (including books or articles) that have been accepted for publication, but not yet published, should indicate where they will be published and have the term “in press” in place of volume and page numbers. These must be updated prior to publication, if possible.
Do not add a discussion or comment to a reference.
Suffixes such as Jr, Sr, and III follow author’s initials.
Examples of reference style:
Submit tables in your manuscript file after references. Do not submit them as separate files. As a general rule, tables should not unnecessarily offer duplicate information given within the text. Starting on a new page, type each table on a separate sheet, using double line spacing. Tables should be created in a Word document using the table tool. Do not format tables using tabs and do not submit tables as figures. Tables should be numbered consecutively in Roman numerals by order of citation in the text. Each table must include title, appropriate column headings, and explanatory legends, including definitions of any abbreviations used. References used within tables should be included in the reference list and numbered in consecutive order according to the table citation in the text. Identify statistical measures of variations such as SD and SEM.
Figures and illustrations
Number all figures (graphs, charts, photographs, and illustrations) in the order of their citation in the text. Include a title for each figure (a brief phrase, preferably no longer than 10-15 words). Do not embed figures in the Word document. Figures must be submitted as individual .jpg or .tif files and have a high enough resolution for publishing. Do not submit figures as Word, PowerPoint or PDF files.
Clinical photographs that identify an individual must be accompanied by a signed statement by the patient or guardian granting permission for publication for educational purposes or must be masked to prevent identification of the patient.
Please refer to the Artwork Guidelines for more details.
Any figure that has been published elsewhere should have an acknowledgment to the original source; a copy of the permission to publish the figure, signed by the copyright holder, must accompany the submission.
Preparation of scientific images (clinical images, radiographic images, micrographs, gels, etc.) for publication must preserve the integrity of the image data. Digital adjustments of brightness, contrast, or color applied uniformly to an entire image are permissible as long as these adjustments do not selectively highlight, misrepresent, obscure, or eliminate specific elements in the original figure, including the background.
Figure and illustrations submitted with an article must be original. Image manipulation that may affect data interpretation is a frequent cause of rejection or retraction.
Authors may submit supplementary material to accompany their article. This material should be important to the understanding and interpretation of the report and should not repeat material within the print article. Supplementary material should be original and not previously published and will undergo editorial and peer review with the main manuscript. Supplementary material must be listed on the title page of your submission and should be cited in the manuscript text in parentheses, in a similar way as when citing a figure or a table. Provide a legend for each supplementary material submitted. Supplementary material will not be edited or formatted; thus, the authors are responsible for the accuracy and presentation of all such material.
Expanded datasets and spread sheets, should be supplied in their original format or as PDF.
Type text using Arial font size 10, and single line spaced. The table title should be set in Arial font size 12, and bold. Headings within tables should be set in Arial font size 10 point, and bold. Table footnotes should be set in Arial font size 8, and single line spaced. If a table runs on to subsequent pages, repeat the column headings at the top of each page. Wide tables may be presented using a landscape orientation.
Additional digitized figures and illustration should be supplied according to the technical specifications for figures.
Accepted file formats: .mov, .mpg, .mpeg, .mp4, .wmv, or .avi
Maximum size: 10 MB
Maximum length: 5 minutes
Verify that the videos are viewable in QuickTime or Windows Media Player.
For each video, provide a citation in the appropriate place in the manuscript text where a legend should also be included. If multiple video files are submitted, number them in the order in which they should be viewed.
Patients should not be identifiable, or their pictures must be accompanied by written permission to use the video. It is the author's responsibility to supply video files in the correct format. The Journal will not consider video material not submitted according to specifications.
Authorship: Each person listed as an author should have participated sufficiently in the work to take public responsibility for the content and agree to be accountable for all aspects related to its accuracy or integrity. This participation must include conception and design of the manuscript, data acquisition or data analysis and interpretation, drafting of the manuscript and/or revising it for critically important intellectual content, revision and final approval of the manuscript and statistical analysis, obtaining funding, administrative, technical, or material support, or supervision. Authors who do not meet the above criteria should be acknowledged in the Acknowledgments Section.
If a study has been conducted by a large multicenter group, you should identify the individuals responsible for its submission, who should fully meet criteria for authorship. Authors may also include in a statement individual contributions following the CredIt taxonomy (https://casrai.org/credit/). This statement will be published in the manuscript in the acknowledgements section.
Once a manuscript has been submitted, the order of authorship (including addition or removal of authors) cannot be changed without a written request to the Editorial Office made by the Corresponding Author. Should agreement between authors not be reached, the manuscript will be withdrawn.
Authorship changes cannot be submitted with proof changes. The publisher is not allowed to make such changes and it will delay the publication of your manuscript.
Corresponding author: The corresponding author is responsible for submission and all communication with the Journal regarding that submission. It is the corresponding author’s responsibility to ensure that all authors meet the required authorship criteria indicated above and for ensuring that the conflict of interest disclosures included in the manuscript's disclosures are accurate and up-to-date.
Authors’ Disclosures: Authors are required to include in the Acknowledgement section specific statements in their manuscript regarding:
a) Conflict of interest: Financial conflict of interest may exist if any financial gain is brought to the author or to his/her family, business partners, or employer by direct or indirect commission; stock ownership or options in manufacturing company; involvement in any for-profit or not-for-profit corporation where the author or his/her family is a director or recipient of a grant, including consultant and travel costs reimbursement.
Non-financial competing interest may be political, personal, or intellectual.
b) Funding/Support: Payment or services from a third party (government, commercial, private foundation, etc.) to support the research and the work reported.
We encourage all authors to complete and share with the Corresponding Author the ICMJE Disclosure of Interest form.
Plagiarism, duplicate submission: Research and publication misconduct is considered a serious breach of ethics. The Journal systematically employs iThenticate, a plagiarism detection and prevention software designed to ensure the originality of written work before publication. Manuscripts proved to include plagiarized content will be rejected. Should an article include plagiarized contents or parts copyrighted by other without appropriate permission we may take further appropriate action.
Data availability: authors must ensure that original research data remain available after publication through appropriate archiving. We encourage authors to make their study data available according to FAIR principles to to improve the Findability, Accessibility, Interoperability, and Reuse of digital assets.
To preserve the transparency, reproducibility and integrity of research records we also encourage authors to make their research data available to readers, either by depositing into data repositories or by publishing data and files as supplementary information in this journal.
Research involving human subjects: If manuscripts report research performed on human subjects, human-derived materials, or human medical records, they must have obtained formal review and approval or waiver by an appropriate institutional review board (IRB) or ethics committee and informed consent by all patients involved. This must be included in the Methods section. For investigators who do not have formal ethics review committees, the principles outlined in the Declaration of Helsinki should be followed and stated in the Methods section of the manuscript.
Patient confidentiality protection: When a patient is identifiable in a photograph or in medical records submitted to the Journal, the author(s) must supply the Journal with written permission from all patients (parents or legal guardian for minors) to publish it online and in print or to ensure that personal information and identification is not possible by masking personal data.
Research involving animals: Experimental research performed on animals must comply with the NIH Guide for the Care and Use of Laboratory Animals or equivalent. A statement that research has been performed according to the NIH Guidelines must be included in the Methods section.
Clinical trial registration: All clinical trials must be registered at an appropriate online public registry that should be electronically searchable and includes a minimum of data elements (www.icmje.org/#clin_trials). Trial registry name, registration identification number, and the URL for the registry should be included in the space provided on the online manuscript submission form.
Research Reporting Guidelines: Authors are encouraged to use the relevant research reporting guidelines for the study type provided by the EQUATOR Network. This will ensure that you provide enough information for editors, peer reviewers and readers to understand how the research was performed and to judge whether the findings are likely to be reliable.
The key reporting guidelines are:
Randomized controlled trials (RCTs): CONSORT guidelines
Systematic reviews and meta-analyses: PRISMA guidelines and MOOSE guidelines
Observational studies in epidemiology: STROBE guidelines and MOOSE guidelines

Technical check at submission
All submissions to Journal of Circulating Biomarkers are initially screened by the Editorial Office, who performs an initial technical check based on the manuscript being a) suitable for the journal and its sections, b) with a sound author background and c) complete in all its parts. If it is not deemed appropriate it will be rejected immediately. The Editorial Office will also perform a thorough plagiarism checking using iThenticate by CrossCheck.
All suitable submissions are then assigned to the Editor in Chief who will be in charge of selecting and inviting reviewers, evaluating their comments and finalizing an editorial decision.
Journal of Circulating Biomarkers adopts a single-blind peer review process, which means that the author does not know the identity of the reviewer, but the reviewer knows the identity of the author: reviewers are asked to supply confidential comments and recommendations which will only be visible to the Editor and comments for the authors which are shared in an anonymous way. We invite both external reviewers and members of the Editorial Board, and allow reviewers suggested by authors, although their invitation is decided by the Editors. We allow 7 days for them to agree or decline to perform the review, asking to return their comments within 2 to 4 weeks from acceptance. Reviewer reports are confidential and are not posted with the articles. Editorials and correspondence may be reviewed and accepted by Editor’s decision.
Accepted submissions will be processed and published online after author approval of proofs and payment of publication fees, which are only due after acceptance of the manuscript: the final responsibility for published contents rests with the authors and the statements and opinions are solely those of the individual authors and contributors. Upon acceptance authors receive an Article Processing Charge form and a Licence to Publish which will need to be signed and returned to the Publisher to proceed with the publication process. Journal of Circulating Biomarkers publishes manuscripts under Creative Commons licenses. The standard license for the journal is Creative Commons NonCommercial 4.0 International License (CC BY-NC4.0) which allows others which allows users to Read, print and download, Copy and redistribute the material in any medium or format, Translate (for private use only) and Reuse portions or extracts from the article in other works, quoting original source. Alternative license are available if required to meet particular funder mandates, made at the author’s request.
Accepted submissions are edited by experienced language editing professionals, with a vast experience in the specific field the article reports on. No charge is made to the authors for language editing. The corresponding author will receive proofs, which will include all changes made by the style editor and must be reviewed within 48 hours. It is the corresponding author’s responsibility to ensure that there are no errors in the proofs.
