  1. Data are means (SD), medians (interquartile ranges; 25th-75th) for skewed variables, or proportions for categorical variables. *Differences were assessed using t-tests (for continuous variables) or chi-square tests (for categorical variables); Mann–Whitney tests were performed for the following skewed variables: AST, ALT, GGT, triglycerides and c-reactive protein.
