LEP and fatty liver disease: We obtained that the combination of miR-21-5p or miR-151a-3p with leptin for predict liver stiffness with an AUC of 0.76 for both options, miR-151a-3p with glucose was also the best combination to predict the hepatic fat content with an AUC of 0.81, and miR-126-5p with leptin to predict the presence or absence of hepatic steatosis and therefore, the disease, with an AUC of 0.95.
