Preparing your manuscript
There is no shortage of general advice on the web on how to write all kinds of scholarly medical articles. The most influential resource is the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (ICMJE), and this is the best place to start when sitting down to write a paper.
These guidelines were initiated 30 years ago to save authors the bother of completely reformatting a manuscript when submitting it sequentially to several general medical journals. But now these uniform requirements have now been adopted by more than 800 journals, and they encompass a wide range of editorial policies and advice on publication practice and ethics.
