Evaluation of the diagnostic accuracy of serum tRF-31-U5YKFN8DYDZDD and combined diagnostic model in GC.(A–C) ROC curves for GC diagnosis using serum tRF-31-U5YKFN8DYDZDD, CEA, CA199, and CA724 between GC patients and healthy controls. (D–F) ROC curves for GC diagnosis using serum tRF-31-U5YKFN8DYDZDD, CEA, CA199, and CA724 between GC and gastritis patients. (B, C, E, F) Combined diagnostic efficacy of serum tRF-31-U5YKFN8DYDZDD, CEA, CA199, and CA724 exerted the best diagnostic efficacy in distinguishing GC patients and non-malignant disease.
