WGCNA identifies key gene modules correlating with RIB and each radiomic feature. a No outlier was detected in sample clustering. b Gene dendrogram after clustering showed twenty-nine gene modules, and each color indicating one gene module. c Counts for each gene module. d Module trait relationships were evaluated by correlations between module eigengenes and RIB score or each radiomic feature. P < 0.05 represents statistical significance, which were marked by red frame
