Furthermore, we conducted an ROC analysis of the predictions by the 20-gene model in 27 responders and 6 non-responders in the validation cohort, which showed a highly significant ability to discriminate responders from non-responders in the cohort (AUC = 0.815, 95 % CI = 0.662–0.968; P = 0.0173; Fig. 1 G).
