EDN1 and Hypertension: The correlation analysis indicated that the serum miR-483-3p level in hypertension patients (cohort 2) was positively correlated with NO and FMD (r = 0.4724, P = 0.0014 for NO; r = 0.5404, P = 0.0002 for FMD) (Figures 2(e) and 2(g)), while it negatively correlated with ET-1 and baPWV (r = −0.4981, P = 0.0007 for ET-1; r = −0.4975, P = 0.0007 for baPWV) (Figures 2(f) and 2(h)).
