In the multivariate logistic regression model (Table 5), HCV coinfection was confirmed to be independently associated with a higher risk of developing liver toxicity (aOR = 8.00, 95%CI 1.27–50.29; p = 0.027), whereas ABCB1 CT/TT genotypes (aOR = 0.10, 95%CI 0.02–0.47; p = 0.004) has been associated with a lower risk; a higher body mass index (aOR = 0.72, 95%CI 0.519–1.000; p = 0.050) has been barely related to a lower risk (Table 5). Here, ABCB1 is linked to hepatotoxicity.
