A Nomogram model of EC patients for predicting the 1 year, 3 year, and 5 year OS rates. To predict the 1 year, 3 year, and 5 year OS rates of EC patients, locate the patient’s LMR on the “LMR” axis. Draw a straight line up to the “point” axis to determine the points for “LMR”. Repeat the process for each of the remaining axes, drawing a straight line each time to the “point” axis. Add the points received from each variable and locate this point on the “total point” axis. A straight line is drawn down from the “total point” axis to the “1 year OS”, “3 year OS”, and “5 year OS” axis to determine the 1 year, 3 year, and 5 year OS rates of EC patients. Calibration curves of the nomogram in the training cohort B 1 year OS, C 3-year OS, D 5 year OS; Calibration curves of the nomogram in the validation cohort E 1-year OS, F 3 year OS, G 5-year OS. The X-axis represents the model − predicted survival, and the Y − axis represents actual survival. The bar represents 95% CI measured by Kaplan–Meier analysis, and the dotted line represents the ideal reference line. H Nomogram model of EC patients for predicting the 1 year, 3 year, and 5 year PFS rates. Calibration curves of the nomogram in the training cohort I 1 year PFS, J 3 year PFS, K 5 year PFS; Calibration curves of the nomogram in the validation cohort L 1 year PFS, M 3 year PFS, N 5-year PFS
