Fig. 1. Data extraction, analysis, and visualization. (A) Data extraction from Cochrane Database Systematic Reviews. The frequency of acupoint use was calculated as the number of studies using a certain acupoint in each study divided by the total number of studies. The frequency of acupoint use was shown to the 361×30 matrix table (361 acupoints and 30 diseases). The 12 Source acupoints data were extracted from a total of 361 acupoints. (B) Correlations between selection patterns of the 12 Source acupoints were calculated. (C) Using hierarchical clustering and multidimensional scaling, the characteristics of Source acupoints were analyzed based on the similarity of the rela-tionships between the Source points and the diseases.
