  • Note: ALT = alanine aminotransferase, AST = aspartate aminotransferase, CI = confidence interval, NS = not significant in univariate analysis, OR = odds ratio, SWE = shear wave elastography.

  • * Adjusted for age and sex in multivariate models even if either variable was not significant in univariate models.
