Based on genera selected by Boruta, the performance of gastric microbial models in prediction GC was analysed by receiver operating characteristic (ROC) curve analysis. A The discriminatory potential of microbial model in distinguishing GC and SG. B The discriminatory potential of microbial model in distinguishing GC and precancerous lesions, including AG, IM, and IN. C The discriminatory potential of microbial model in distinguishing GC and CAN. SG: superficial gastritis, IM: intestinal metaplasia, GC: gastric cancer, CAN: carcinoma adjacent normal tissues, preGC: precancerous lesions of gastric cancer. AUC: area under the curve
