Objective To systematically review the researches on grading criteria for quality of evidence and strength of recommendations of traditional Chinese medicine (TCM). Methods PubMed, EMbase, Web of Science, CNKI, WanFang Data and VIP databases were electronically searched to collect researches on grading criteria for quality of evidence and strength of recommendations of traditional Chinese medicine from inception to June 2021. Two reviewers independently screened literature, extracted data; and then, descriptive analysis was performed using qualitative methods. Results A total of 18 studies were included. Specifically, 8 studies presented both the level of evidence and the strength of recommendations, 9 presented the level of evidence, and 1 presented the strength of recommendations. Thirteen studies considered both TCM evidence and modern medical evidence sources, 3 included only evidence from ancient literature, 1 focused only on post-marketing safety evaluation of Chinese medicine, and 1 focused only on real-world studies of TCM. Conclusion Currently, there are numerous criteria for TCM related quality of evidence and strength of recommendations, and some are developed only for TCM characteristic evidence. Most researchers of TCM guidelines expect to fully value the significance of ancient literature and expert experience or opinion in guideline development.
