Using receiver operating characteristic (ROC) analysis to examine candidate hub genes. The x-axis represents specificity, the y-axis represents sensitivity, and AUC represents the area under the curve. A ROC curves of three candidate genes (ITGA11, THBS2, VCAN) in GSE122897. B ROC curves of three candidate genes (ITGA11, THBS2, VCAN) in GSE237229. C Validation of the most significant diagnostic gene, ITGA11, in datasets GSE75436 and GSE57691
