Characteristic curves of PG I level and PG I/II ratio for discriminating gastric cancer. The optimal cut-off points of PG I level and PG I/II ratio were determined by analysis of receiver operating characteristic (ROC). The discriminatory ability did not differ between PG I and PG I/II values, with areas under the ROC curves of 0.880 and 0.876, respectively (p = 0.28).
