Performance of the models using cell-free miRNA data. From (A) to (C) 5-fold cross-validated Kaplan–Meier curves for the models derived using the miRNA data alone, miRNA and and basic prognostic factors (age, sex, and pathologic stage) data, and the prognostic factors data alone. From (D) to (F) Five-fold cross-validated time-dependent ROC curves (at 24 months) for the three models. DFS disease-free survival, TP true positive, FP false positive
