Notes: AUC Area-under-the-curve, CI confidence intervals, PG Pepsinogen, AG Atrophic gastritis, GC Gastric cancer, C Normal control. The diagnostic value of variables was analyzed by receiver operating characteristics (ROC) analysis. Youden index was used to determine the optimal cutoff value (Cut off). A P < 0.05 was considered as statistically significant
