Multidimensional cluster analysis based on the SUCRA values of any three outcomes of different CHIs was performed with the “scatterplot3d” package in R 4.0.3 software to comprehensively assess efficacy. The K-means method was adopted to cluster these interventions, and the number of clusters was modified according to the actual situation. The steps of clustering were as follows: (1) The included interventions were randomly divided into k initial categories, and the initial aggregation points were the average of the outcome of these k categories. (2) An intervention was classified into the closest aggregation point category and then the aggregation points of the category were updated to the average of the current outcome indicators. All interventions were recategorized and classified, and step (2) was repeated until all interventions were assigned. Finally, the ranking of the interventions for the three outcome indicators was visualized with a three-dimensional stereogram.
