Background: Evidence mapping is a comprehensive evidence research method that systematically collects, evaluates, and synthesizes existing evidence to clarify research status and gaps, thereby promoting scientific research and decision-making. There are relatively few theoretical and practical researches, and the concept definition is inconsistent.

Objectives: This article will systematically introduce the methodology of evidence mapping production and reporting for researchers to use for reference.

Methods: Literature review and analysis.

Results: At present, the production steps and definitions of the evidence mapping are not uniform. On the whole, the evidence mapping is mainly divided into two types, one is the evidence map and the other is the gap map. The production steps mainly include: develop scope, set exclusion criteria, searching, assessing inclusion, critical appraisal, and producing.

Conclusions: Evidence maps are versatile and deserve the attention of researchers and decision makers.
