TIPRL and gastric cancer: Moreover, in receiver operator characteristic (ROC) curve analysis, which plots the area under the curve (AUC) to evaluate the diagnostic value of TIPRL in gastric cancer, clear separation was observed between normal and gastric cancer tissues, with an area of 0.6490 [Figure 2H, CI (95%): 0.5709–0.7270, P = 0.0004].
