Comparison of AUCs for gastric cancer development among single tests using serum PG status and H. pylori antibody. The AUCs were compared among PG I, PG II, PG I/II, and H. pylori antibody titer. The AUCs of the following tests were compared with that of PG I/II (AUC = 0.649 ± 0.017, 95% CI: 0.615-0.683): a, the AUC of PG I (0.561 ± 0.011, 95% CI: 0.526-0.597) was significantly lower than that of PG I/II (p < 0.001); b, the AUC of PG II (0.434 ± 0.018, 95% CI: 0.400-0.469) was significantly lower than that of PG I/II (p < 0.001); c, the AUC of H. pylori antibody (0.574 ± 0.018, 95% CI:0.538- 0.610) was significantly lower than that of PG I/II (p < 0.001)
