Analyses were based on the overall cohort and NAFLD patients.

Displayed OR are adjusted for sex, age, BMI, metabolic syndrome, hepatic steatosis, alcohol consumption, intake of fast-food, vegetables, fruits, sweets, red and processed meat, white meat, fish, coffee and consumption of SSB. OR for Fib-4 score and Forns-Index were not adjusted for age since this variable is included in these indices.

Abbreviations: aOR–adjusted Odds ratio; NAFLD–non-alcoholic fatty liver disease; SSB–sugar-sweetened beverage; T2DM–type 2 diabetes mellitus; 95%CI– 95% confidence interval.
