Predictive markers of nonalcoholic fatty liver disease in lean patients. A multinomial regression model and a 2k factorial analysis.

Objective: Nonalcoholic fatty liver disease (NAFLD) is associated with obesity and insulin resistance; however, there is a group of non-obese patients with NAFLD that need to be characterized. Our aim was to evaluate the factors associated with NAFLD in non-obese subjects in a third-level hospital.

Methods: A comparative cross-sectional study was performed.
