CMAJ. Canadian Medical Association Journal

Aims & Scope

Scientific articles should conform to theInternational Committee of Medical Journal Editors (ICMJE) recommendationsfor manuscripts submitted to biomedical journals. TheCanadian Medical Association Journal(CMAJ)also follows theCommittee on Publication Ethics(COPE) guidelines. If your article contains previously published material (table, figure, appendix, box) or modified material, you must obtain permission from thepublisher and/or copyright or licence holder.CMAJGroup'srequirements are as follows: See below for details on howletters,clinical guidelines, andsupplementsare handled. Maximum length:Research manuscripts should be written clearly but succinctly, particularly in the Introduction and Interpretation sections, with the Methods and Results sections comprising more than half of the main text. Excessively long manuscripts are less appealing to readers and risk making a negative impression on external peer reviewers. At submission, manuscripts should ideally be no longer than 2,500 words, excluding title page, abstract, figures, tables, appendices and references. For certain study designs, including systematic reviews, qualitative studies and economic analyses, we permit a maximum length of 3,500 words. Accepted manuscripts may be published as a synopsis in print, with complete versions appearing online. Registration:CMAJasks that reports of randomized controlled trials adhere toCONSORTguidelines and requires treatment trials to be registered in a clinical trials registry. For more information, seeClinical Trial Registrationon the ICMJE website.Data-sharing: We also require authors of clinical trials of drugs and medical devices to provide a data-sharing statement that indicates (1) whether any, all or portions of the data are available to others; (2) where, through whom, when and on what terms data will be available; (3) how data may be accessed. Systematic reviews and meta-analyses should attempt to answer a focused question and adhere toPRISMAmethods. Where p
