This paper summarizes the main features of review articles in medical topics. Articles can be classified as narrative reviews, systematic reviews or meta-analysis. Narrative reviews are appropriate to update etiology, pathophysiology or clinical aspects of diseases, and advances in basic and preclinical sciences. ⋯ No meta-analysis had been published in these periods, in this journal. Meta-analysis including primary studies performed in Chile by Chilean investigators have been published in English language in other medical journals. The educational and professional role of review articles is recognised, with a word of caution on a strict adherence to ethical rules adopted by scientific and clinical publications, mainly with respect to authorship and potential conflicts of interest.
