(A) miRNA included within the model. (B) Model performance (n = 175; AUC 0.83 [95% CI 0.76–0.89; p <0.0001*]; pseudo r2 = 0.2767, HL statistic 11.54 [p = 0.17]). (C) MetaCore™ pathway analysis including miRNA within the model. (D) Comparisons with other outcome prediction models with and without threshold values using the DeLong method. Statistical significance set as per Benjamini-Hochberg procedure with a false discovery rate of 0.05 (*p <0.026).
