Fig. 1From: Serum apelin is associated with left ventricular hypertrophy in untreated hypertension patientsThe ROC curve of serum apelin level. Serum apelin at 1.92 ng/mL is excellent to discriminate LVH prevalence in hypertensive patients, with 78 specificity and 82 % sensitivity. The AUC value was 0.809 (95 % CI = 0.76 to −0.85, P < 0.001)Back to article page
