Cox regression identified independent prognostic factors for nomogram development. The nomogram\u2019s predictive accuracy and discriminative capability were evaluated through Harrell\u2019s concordance index (C-index), calibration plots, and decision curve analysis, and its performance was compared to the International Federation of Gynecology and Obstetrics (FIGO) staging system.

The Harrell\u2019s C-index of nomogram was 0.817 (95% confidence interval [CI], 0.762\u20130.873), which was higher than that of FIGO staging system 0.700 (95% CI, 0.637\u20130.764,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0&amp;lt;\u00a00.001). Moreover, the nomogram showed superior performance in decision curve analysis (DCA) and a higher area under the curve (AUC) compared to the FIGO staging system. The calibration curve for survival probability exhibited good consistency between the probabilities and observed values.
