Open Access Macedonian Journal of Medical Sciences (OAMJMS) [formerly known as Macedonian Journal of Medical Sciences] is a top-tier open access medical science journal published by the ID Design 2012/DOOEL Skopje, Naroden Front No. 13/45, 1000 Skopje, Republic of Macedonia. OAMJMS is an international, modern, general medical journal covering all areas in the medical sciences, from basic studies to large clinical trials and cost-effectiveness analyses. We publish mostly human studies that substantially enhance our understanding of disease epidemiology, etiology, and physiology; the development of prognostic and diagnostic technologies; trials that test the efficacy of specific interventions and those that compare different treatments; and systematic reviews. We aim to promote translation of basic research into clinical investigation, and of clinical evidence into practice. We publish occasional studies in animal models when they report outstanding research findings that are highly clinically relevant. Our audience is the international medical community as well as educators, policy makers, patient advocacy groups, and interested members of the public around the world. OAMJMS is published quarterly online and in print version.
