Construction and validation of the pyroptosis-related 6-gene‑based nomogram. The forest plots for univariate (A) and multivariate (B) Cox Hazard Regression analysis of overall survival (OS), based on the 6-gene signature and clinical characteristics, including age, pathological grade, and clinical FIGO stage. (C) The prognostic nomogram model for 1-year, 3-year, and 5-year OS of ovarian cancer (OV) patients, based on the 6-gene risk score and clinical indicators selected by the Cox Regression analysis. (D) The calibration diagrams of the prognostic nomogram for predicting 1-year, 3-year, and 5-year OS (top, middle, and bottom) among OV patients. (E) The Kaplan-Meier (K-M) curves (left) and Receiver Operating Characteristic (ROC) curves (right) for patients in the TCGA-OV training cohort, classified by the prognostic nomogram score. (F) The K-M curves (left) and ROC curves (right) for patients in the ICGC-OV validation cohort, related to the nomogram score
