¹Described by mean ± SD or n (%).

²Indicates hepatitis B virus, autoimmune, cholestatic disease, non-alcoholic fatty liver disease, and cryptogenic.

³Indicates association statistically significant by the test of the residuals adjusted to 5% of significance. PA: Phase angle; HCV: Hepatitis C virus.
