GPT and fatty liver disease: Every 1.0 kg of weight loss significantly correlated with a 0.83-unit (95% confidence interval [CI]: 0.53 to 1.14, p < 0.001) reduction in alanine aminotransferase (ALT) (IU/L) and a 0.77 percentage point (95%CI: 0.51 to 1.03, p < 0.001) reduction in hepatic steatosis measured by histology or magnetic resonance imaging (MRI) [9].
