Developed a genomic signature based nomogram and the performance of the nomogram. (a) The nomogram was designed in the learning set, with the 23-mRNA biosignature based risk score and Lauren classification integrated. (b) The area under curve of nomogram in learning set was 0.916 (95% CI: 0.833–0.999). Area under curve of nomogram in verification set was 0.775 (95% CI: 0.647–0.903). (c) Calibration plot in learning set (mean absolute error = 0.021). After 1000 repetitions of bootstrap, the bias-corrected calibration curve (solid line) was close to the ideal curve (dashed line). (d) Calibration plot in verification set (mean absolute error = 0.039)
