Chen LD, et al. - This trial was initiated in order to inspect the association between obstructive sleep apnea (OSA) and nonalcoholic fatty liver disease (NAFLD) and the effect of continuous positive airway pressure (CPAP) therapy on serum aminotransferase levels in OSA patients. An independent correlation was discovered between OSA severity with liver steatosis and elevation of serum aminotransferases. 3 months of CPAP therapy disclosed a link with a statistically prominent improvement on the liver injury in OSA patients.
