Combined detection of P53, Ki67, P504S, and IMP3: Diagnostic implications for gastric cancer and precursor lesions

Figure 4 Receiver operating characteristic curves of the four proteins in predicting gastric mucosal biopsies. A: Receiver operating characteristic (ROC) curves of P504S, Ki67, and their combination in predicting low-grade dysplasia; B: ROC curves of P53, IMP3, and their combination in predicting high-grade dysplasia/adenocarcinoma. ROC: Receiver operating characteristic; AUC: Area under the curve.
