To systematically evaluate the distribution of traditional Chinese Medicine (TCM) constitutions in stable chronic obstructive pulmonary disease (COPD),and to provide evidence-based evidence for the prevention and treatment of COPD by TCM.Methods:A total of 4 Chinese and English databases,including CNKI,WAN FANG,VIP,and Pubmed,were searched by computer using a comprehensive retrieval strategy.A total of 2 researchers independently searched,screened,and extracted the literature on the correlation between TCM constitution and chronic obstructive pulmonary disease worldwide.Stata13.0 software was used to conduct a meta-analysis on the combined effect sizes of included studies,and subgroup analysis and sensitivity analysis were used to explore possible sources of greater heterogeneity.Finally,Begg,Egger methods were used to detect publication bias.Results:After strict inclusion and exclusion criteria,17 cross-sectional studies were included,with a total of 5,077 patients.AHRG evaluation criteria were used to evaluate the methodological quality of the included studies,including two high quality and two low-quality studies,and 13 medium quality studies.The proportion and 95% confidence interval of TCM constitution types in stable COPD patients were qi-deficiency 28%［95%CI（24%，32%）］,yang-deficiency 21%［95%CI（17%，25%）］,phlegm-dampness 14%［95%CI（11%，18%）］,yin-deficiency 10%［95%CI（7%，13%）］,and damp-heat constitution 8%［95%CI（6%，10%）］.Besides,there are differences in the distribution of TCM constitutions of COPD by gender and region.The findings of Begg's,Egger's showed no significant publication bias.Conclusion:Qi-deficiency,yang-deficiency,phlegm-dampness,and yin-deficiency are the main types of biased constitutions in COPD at a stable period,and some TCM constitutions are different in gender and region.To improve the quality of literature,it is suggested that the related research should follow the EBM standard of a cross-sectional study.
