UCA1 and coronary artery disorder: Further ROC curve analysis indicated that lnc‐UCA1 (area under curve (AUC): 0.897, 95% confidence interval (CI): 0.856–0.937, Figure 2), miR‐26a (AUC: 0.834, 95% CI: 0.777–0.892), and miR‐195 (AUC: 0.668, 95% CI: 0.591–0.745) all could distinguish the patients with CHD from controls, among which lnc‐UCA1 exhibited the highest AUC.
