Abstract
BackgroundWe explored the changes in metabolic dysfunction-associated steatotic liver disease (MASLD) severity over time by analyzing data from the placebo arms of randomized controlled trials (RCTs), focusing on the presence of diabetes.MethodsRCTs on MASLD that included a placebo arm were identified using a systematic search of the literature. Primary outcomes were changes in hepatic steatosis and fibrosis.ResultsThe meta-analysis included 8 RCTs involving 386 patients without diabetes and 24 RCTs involving 637 patients with diabetes. The pooled estimate of mean change in steatosis grade was − 0.1 in patients without diabetes, and − 0.37 in patients with diabetes (P = 0.066). The mean change in fibrosis stage was 0.05 in patients without diabetes, and − 0.03 in patients with diabetes (P = 0.359). The mean change in nonalcoholic fatty liver disease activity score was − 0.55 in patients without diabetes, and − 1.50 in patients with diabetes (P = 0.100). The mean change in ALT and AST were significantly larger in patients without diabetes compared to those with diabetes (P < 0.05).ConclusionPlacebo treatment had a greater effect in improving liver steatosis in patients with diabetes compared to those without. These findings highlight the importance of tailored treatment strategies in MASLD, particularly considering diabetes status.
