H19 and in situ carcinoma: To evaluate the ability of serum lncRNA MIAT and H19 levels to differentiate between hypertensive and non-hypertensive CIS cases, ROC curve analysis revealed an AUC of 0.542 (95% CI = 0.414–0.67) at p = 0.519 and 0.69 (95% CI = 0.572–0.8) at p = 0.003, respectively (Figure 4).
