Since 1973, Revista Médica de Chile has classified biomedical and clinical prospective research papers in a Section named "Research Articles", while purely clinical and retrospective studies were classified into another Section, named "Clinical Experiences". This distinction seems no longer necessary, because both types of manuscripts are subjected to a uniform external peer-review system and their intrinsic quality is not a distinctive feature. Furthermore, the name of Sections where similar papers are classified by the major general clinical medicine journals is clearly non-uniform. Therefore, "Research Articles" and "Clinical Experiences" will from now on be included into a single Section: "Research Articles". (Rev Méd Chile 2000; 128: 7-8)
