Gut microbiota composition associated with hepatic fibrosis in non‐obese patients with non‐alcoholic fatty liver disease

Background and Aim Gut microbiota composition is associated with the pathogenesis of non‐alcoholic fatty liver disease. However, the association between gut microbiota composition and non‐alcoholic fatty liver disease in non‐obese patients remains unclear. We compared clinical parameters and gut microbiota profiles of healthy controls and non‐obese and obese patients with non‐alcoholic fatty liver disease. Methods We examined the clinical parameters and gut microbiota profiles by 16S rRNA sequences and short‐chain fatty acid levels in fecal samples from 51 non‐obese patients with non‐alcoholic fatty liver disease (body mass index
