The rising number of medical publications makes it difficult to keep up-to-date on scientific knowledge. In recent years, reviews in the form of narrative or systematic publications and meta-analyses have increased. These can only be interpreted and evaluated if the reader understands the techniques used. This review article describes the differences between narrative and systematic reviews, together with the characteristics of meta-analysis, and discusses their interpretation. The concept of systematic reviews and meta-analysis includes a systematic literature search and summary, together with an appraisal of the quality of the publications. Systematic reviews are often considered to be original studies due to their structure and ability to reduce bias.
