For HP+/- patients, ROC curves of serum TFFs and PG I/II ratio. (A) For HP positive patients, the area under the curve for serum TFF1, TFF2, TFF3 and PG I/II ratio was 0.67, 0.72, 0.83 and 0.86, respectively. Serum TFF3 and PG I/II ratio showed a good ROC curve. (B) For HP negative patients, the area under the curve for serum TFF1, TFF2, TFF3 and PG I/II ratio was 0.64, 0.75, 0.77 and 0.72, respectively.
