Abstract
The increasing production of primary research and literature reviews in the last decades has made it necessary to develop a new methodological design to synthesize the evidence: the overviews. An overview is a type of evidence synthesis that uses systematic reviews as the unit of analysis, with the aim of extracting and analyzing the results for a new or broader research question, helping the shared decision-making processes. The aim of this article is to introduce the reader to this type of evidence summaries, high-lighting the differences between overviews and other types of synthesis, the unique methodological aspects of overviews, and future challenges. This is the twelfth article from a collaborative methodological series of narrative reviews about biostatistics and clinical epidemiology.
