Kaplan-Meier curves of Radscore (A) and Nomogram (B) in high-risk and low-risk group. Kaplan-Meier analysis of progression free survival (PFS). (A) Kaplan-Meier curves comparing PFS between high-risk Radscore group (blue line) and low-risk Radscore group (red line). (B) Kaplan-Meier curves comparing PFS between high-risk Nomogram group (blue line) and low-risk Nomogram group (red line). As p<0.0001 indicated significant difference of PFS between high-risk group and low-risk group in Rad-score and nomogram model. Besides, as time went on, the high-risk group was prone to with shorter PFS.
