Comparison of the diagnostic performance of a previously identified 5-microRNA ratio biomarker panel (Chiam et al[20]) for detecting esophageal adecarcinoma. A: The diagnostic accuracy of the biomarker panel was assessed by receiver-operating characteristics curve analysis. The area under the curve was greater in the serum than the plasma; B: The biomarker panel was assessed by leave-one-out-cross validation. The serum small extracellular vesicle preparations produced greater diagnostic accuracy than the plasma small extracellular vesicle preparations. Healthy individuals, n = 10; esophageal adenocarcinoma, n = 10. AUC: Area under the curve.
