Distribution, calibration, and discrimination of the GCRS in the CKB and Changzhou cohorts. a, d Distribution of the GCRS between incident gastric cancer (GC) cases and GC-free participants in the a CKB and d Changzhou cohorts. b, e The observed 10-year probability of GC with 95% CIs was estimated by the Kaplan-Meier method within deciles of GCRS-based model-predicted probability in the b CKB and e Changzhou cohorts. c, f Receiver operating characteristic curve at 10 years in the c CKB cohort (Harrell’s C-index of 0.754, 95% CI 0.745–0.762) and f Changzhou cohort (Harrell’s C-index of 0.736, 95% CI 0.710–0.761).
