Nomogram model for predicting overall survival of patients in CGGA dataset. a A nomogram that integrates the signature risk score with the clinicopathologic characteristics. The ‘point’ represents the impact of each variable on patients’ survival. The line determines the ‘point’ received from the value of each variable. The sum of the individual points is presented as ‘total points’. The line drawn downward to the survival axis finally determines the likelihood of different survival rate. b The calibration curve for the nomogram model. Three colored lines (blue, red and black) represent the performance of the nomogram. A closer fit to the diagonal line (gray) indicates a better estimation
