Characteristics of the study population.
<p>Abbreviations: ALT, alanine aminotransferase; ARV, antiretroviral; HBe-Ag, Hepatitis B envelope antigen; HBsAg, Hepatitis B surface antigen; HCV, Hepatitis C virus; y, years.</p><p>Data are presented as median (interquartile range) for continuous variables and as count (column percentage) for categorical variables. P values hypothesis testing between HBsAg positive and HBsAg negative are derived from Mann-Whitney U test for continuous and χ2-test for categorical variables.</p
