Fig. 8From: MRI-based random survival Forest model improves prediction of progression-free survival to induction chemotherapy plus concurrent Chemoradiotherapy in Locoregionally Advanced nasopharyngeal carcinomaKaplan-Meier curves of different stratification methods. Note: The Kaplan–Meier survival analysis is conducted to estimate the high- and low-risk PFS in the training and testing cohorts.
