Performance of DRS-BCR for predicting 3-year BCR-free survival. (a–c) The Kaplan–Meier (K–M) curves of DRS-BCR-free survival for BCR-free survival within three years in the primary cohort, validation cohort 1, and validation cohort 2, respectively. The p values were calculated by log-rank test between subgroup with high-risk and low-risk, and significant discrimination was revealed by p values less than 0.05. (d–f) The calibration curves for 3-year BCR. (g–i) Clinical benefits by decision curve analysis for 3-year BCR. DRS: deep radiomic signature; BCR: biochemical recurrence.
