Clinical, anthropometric, biochemical, and histological characteristics of nonobese nonalcoholic fatty liver disease patients of Bangladesh

Background Nonalcoholic fatty liver disease (NAFLD) is considered to be a disease of obese individuals, yet lean patients are increasingly susceptible to have NAFLD.
