Serum Micro-RNA-122 Level as a Simple Noninvasive Marker of MAFLD Severity.

Background: Metabolic-associated fatty liver disease (MAFLD) is a common disease worldwide. Micro-RNA-122 is known to be the most abundant micro-RNA expressed in the liver.

Objective: To evaluate the association of micro-RNA-122 and the degree of steatosis and fibrosis in obese patients with MAFLD.
