What article types do you accept? What checks will my manuscript undergo prior to posting?

We currently accept the following:

• Research Article - a full article of the kind that appears in academic journals. Research Articles usually take the form of Introduction, Methods, Results, Discussion, and Conclusions.
• Systematic Review - a formal evaluation of the literature on a particular topic, including clearly defined inclusion/exclusion criteria, an exclusion flowchart, and a meta-analysis of available results.
• Method Article - a full description of a new method. A Method Article should include a write-up of the steps taken to validate the method, with results to support this validation.
• Short Report - a brief write-up of a single experiment. This often takes the form of a single figure with brief accompanying text to explain how the figure was obtained.
• Case Report - a write-up of an individual clinical presentation. This is usually accompanied by a literature review to place in the context of current clinical understanding.
• Data Note - a single dataset accompanied by a brief write up of how the data were obtained.

We do not accept literature reviews, hypotheses, opinions, theories, or commentaries.

Additionally, checks include an assessment of whether a manuscript is an acceptable article type, has the appropriate declarations where necessary (such as ethics approval, consent statements, and competing interests disclosures), and has all figures, tables, and supplemental material referenced in the manuscript. All manuscripts will also be checked to ensure there is no potential for human harm.

Please note: posting the exact same preprint on multiple servers is generally discouraged by major repositories and publishing guidelines, though copyright laws usually allow you to do so.
