Association of the studied genotypes and variables of the anti-tuberculosis drug- induced liver injury treatment in the samples of the patients under treatment of TB included in the study.

Variable	OR (95% CI)	p-value (<0.10)
CYP2E1 Variant	4.57 (0.75–27.6)	0.09*
NULL GSTM1	0.58 (0.06–5.58)	0.6
NULL GSTT1	4.57 (0.76–27.6)	0.09*
Use of illicit drugs	0.39 (0.06–2.36)	0.3

Every patient who had at least one variant allele, regardless of the region, due to low frequency, was considered a variant genotype of CYP2E1. A p-value < 0.10 was considered significant due to the reduced number of patients included in the study.
