Fig. 3From: A three-miRNA signature as promising non-invasive diagnostic marker for gastric cancerSelection and validation of (a) miR-18a, (b) miR-140-5p, (c) 199a-3p, (d) miR-627, (e) miR-629 and (f) miR-652 in an independent validation set (VS). Box plots and ROC curve analysis of miRNAs in the plasma of gastric cancer patients (n = 58) and healthy controls (n = 46). The boxes mark the interval between the 25th and 75th percentiles, and the lines inside the box denote the medians. The whiskers represent the interval between the 10th and 90th percentiles. Statistically significant differences were analyzed using Mann–Whitney test.
