Figure 4. Clinical association of CRRS. (A) The heatmap indicating CRRS was significantly associated with age, gender, tumor grade, tumor stages, pathological T stages, and M stages utilizing Chi-square tests. (B–F). The time-dependent ROC analyses indicated the CRRS showed superiority over other clinical features in predicting the 1- (B), 2- (C), 3- (D), 4- (E), and 5-year (F) overall survival rate. ROC, receiver operating curve; CRRS, circadian rhythm-related score. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
