Figure 7 Calibration curves for the overall survival nomogram at 9-, 12-, and 18-month.
Patients were stratified into quartiles according to nomogram-predicted survival probability. Points represent the mean predicted probability vs Kaplan-Meier-observed survival for each quartile; error bars indicate 95% confidence intervals. The dashed diagonal represents perfect calibration. Original concordance index (C-index) = 0.792; 1000-bootstrap optimism-corrected C-index = 0.779 (optimism = 0.026). K-M: Kaplan-Meier; C-index: Concordance index.
