Original research article

Previously unpublished manuscripts, describing clinical, pre-clinical, epidemiological investigations, clinical trials, clinical observations, and other relevant investigations that are based on sound patient series, validated analytical methods, and appropriate statistical evaluation. Systematic reviews and meta-analysis can also be submitted as an original research article. Original research articles should be structured as follows: Introduction (clearly stating an objective or hypothesis), Methods (describing the study design and methods applied, including the study setting and dates, patients or participants with inclusion and exclusion criteria, and/or participation or response rates, or data sources, and how these were selected for the study), Results (describing the results of the study in context with the published literature and addressing study limitations), and Conclusions (addressing relevant implications for clinical practice or health policy). A structured abstract (250 words) is required.
