SCLC
The nomograms predicting OS (Figure (A) Nomogram predicted 8‐, 12‐, and 24‐month OS for SCLC patients. The total points predicted on the bottom scale represent the probability of 8‐, 12‐, and 24‐month survival rates. (B–D) Calibration curves for predicting 8‐(B), 12‐(C), and 24‐month (D) OS of SCLC patients in the training cohort. The X‐axis denotes survival predicted by the nomogram and the Y‐axis represents actual OS as measured by the Kaplan–Meier analysis. (E–G) Calibration curves for predicting 8‐(E), 12‐(F), and 24‐month (G) OS of SCLC patients in the validation cohort.(A) Nomogram predicted 6‐, 12‐, and 18‐month PFS for SCLC patients. (B–D) Calibration curves for predicting 6‐(B), 12‐(C), and 18‐month (D) PFS of SCLC patients in the training cohort. (E–G) Calibration curves for predicting 6‐(E), 12‐(F), and 18‐month (G) PFS of SCLC patients in the validation cohort.
