To further identify the diagnostic efficiency of MALAT1 expression in HTN patients, the diagnostic relation between MALAT1 and HTN was assessed by ROC curve, outcome of which unraveled that the AUC was 0.847 and 50% confidence interval (CI) was 0.746-0.947 (P < 0.001); sensitivity and specificity were 0.700 and 0.933, implying that lncRNA MALAT1 may be an effective biomarker in the diagnosis of HTN (Figure 1B). The gene discussed is MALAT1; the disease is hypertensive disorder.
