Circ_0004592: An auxiliary diagnostic biomarker for gastric cancer

Figure 5 The diagnostic utility of plasma circ_0004592 in gastric cancer patients. A: Evaluation of diagnostic efficiency of circ_0004592 in differentiating gastric cancer (GC) patients from healthy donors; B: Evaluation of diagnostic efficiency of carcinoembryonic antigen (CEA) in differentiating GC patients from healthy donors; C: Evaluation of diagnostic efficiency of CEA in differentiating GC patients from healthy donors; D: The combined diagnosis of circ_0004592, CEA and cancer antigen 199 in discriminating GC patients from healthy donors. ROC: Receiver operating characteristic; CEA: Carcinoembryonic antigen; CA199: Cancer antigen 199; AUC: Area under the curve; 95%CI: 95% confidence interval.
