The journal publishes 6 regular issues per year (bimonthly). Contents include original research papers (original articles and case reports) mainly focused on clinical practice and epidemiology, but also on basic research, updates (reviews) and other sections, such as Letters to the Editor, Clinical rheumatology in images and Special articles. The journal, indexed in Medline, follows the publication requirements of the International Committee of Medical Journal Editors (ICMJE) and the Committee on Publication Ethics (COPE).
