Construction of immune-related gene pairs signature to predict the overall survival of osteosarcoma patients

Figure 5. Construct and evaluate nomograms in TCGA and GSE21257 cohort. (A) Nomogram to predict the probability of TCGA patients mortality based on IRGP and clinical variables. (B) The calibration plot for internal validation of the nomogram. (C) Decision curve analyses of the nomograms based on IRGP signature for 3-year overall survival. (D) The calibration plot of the nomogram in the GSE21257 data set is used for external verification. *P<0.05, **P<0.01, ***P<0.001.
