From: Urinary exosome miR-146a is a potential marker of albuminuria in essential hypertension
ROC analysis of urinary microRNA expression in extracellular vesicles from normalbuminuric and microalbuminuric hypertensive patients. Receiver operator characteristic (ROC) curves were constructed using the microRNA expression values for miR-146a in exosomes (a) and microvesicles (b). The area under the curve (AUC) and 95% CI were computed and are shown for each ROC curve. The Wilcoxon and Mann–Whitney U tests were used to test the null hypothesis that the AUC is equal to 0.5, and the probability values for each test are shown
