ROC curves for concentration of serum TFFs and PG I/II ratio to diagnose gastric cancer or CAG. (A) ROC curves for concentration of serum TFFs to diagnose gastric cancer compared with PG I/II ratio. The area under the curve of serum TFF1, TFF2, TFF3 and PG I/II ratio was 0.67, 0.74, 0.81 and 0.78, respectively. The results showed that serum TFF3 has a greater predictive power for gastric cancer than PG I/II ratio. (B) ROC curves for concentration of serum TFFs and PG I/II ratio to diagnosis CAG. The area under the curve of TFF1, TFF2, TFF3 and PG I/II ratio was 0.63, 0.61, 0.53 and 0.76, respectively. The results presented that PG I/II ratio is an obviously better marker for CAG detection than all of serum TFFs.
