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

Nonalcoholic fatty liver disease (NAFLD) is considered to be a disease of obese individuals, yet lean patients are increasingly susceptible to have NAFLD. The aim of this study was to evaluate the profile of nonobese patients by comparing with obese NAFLD patients.
