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. Include figures and legends in the word file where they are cited. Save your manuscript as a Word document (.doc, .docx, or previous; Open Office or RTF formats).
All submissions should consist of one file which must include title page, text, references and additional elements as required and indicated below.
It must include the following information:
We encourage all authors to complete and share with the Corresponding Author the ICMJE Disclosure of Interest form.
Divide the text as indicated for each content type and structure your manuscript file in Manuscript Text, Figure legends, Tables, and Referencese commas (,) to separate thousands and full stop (.) for decimals (e.g. 12,354.55). Include tables in the manuscript file, before the references. Number all figures (graphs, charts, photographs, and illustrations) in the order of their citation in the text. Please embed your figures and graphs in the manuscript and supply them as high-resolution separate files.
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 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, analyting 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.
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.
Research reporting guidelines
Journal of Circulating Biomarkers endorses the EQUATOR Network initiative, which promotes the transparent and accurate reporting of health research. Authors are required to identify the relevant reporting checklist for their study type and ensure that it is completed and submitted along with their manuscript. Adhering to these guidelines enhances the quality and clarity of research reporting, ultimately contributing to the advancement of scientific knowledge.
Figure legends and legends for supplementary material
At the end of the manuscript, include a short title (max 15 words) and a legend (max 300 words) 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.
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 before the reference list. Do not submit tables as separate files. Tables should be created in a Word document using the table tool and using double line spacing. Do not format tables using tabs and do not submit tables as figures.
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. Tables should be numbered consecutively in Arabic numerals by order of citation in the text. Each table must include title (preferably no longer than 10-15 words), appropriate column headings, and explanatory legends (max 300 words), 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.
Larger datasets, or tables too wide for A4 or Letter landscape page can be uploaded as supplementary material.
Figures and illustrations
Figure and illustrations submitted with an article must be original. Number all figures (graphs, charts, photographs, and illustrations) in the order of their citation in the text. Include a title for each figure (preferably no longer than 10-15 words). Figures must be submitted as individual files and have a high enough resolution for publishing. We recommend the following file formats:
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. Any figure that has been published elsewhere should have an acknowledgment to the original source; a copy of the permission to publish itmust 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.
Please refer to the Artwork guidelines for more details.
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. To ensure the integrity of the double-blind peer-review for submissions to AOP ensure to remove personal information from file properties on supplementary material.
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.
