Table 5. Interaction analysis between rs3128935 genotypes and high-risk population or age.

a) rs3128935 genotypes and high-risk population
Variables	Resolver N(%)	Chronic N(%)	OR (95% CI)
TT genotypes with drug using	102 (41.5)	117 (53.7)	1.00
CT/CC genotypes with drug using	52 (21.1)	25 (11.5)	0.40 (0.24–0.74)
TT genotypes with HD	73 (29.7)	57 (26.1)	0.37 (0.20–0.69)
CT/CC genotypes with HD	19 (7.7)	19 (8.7)	0.48 (0.20–1.11)
P for multiplicative interaction			P = 0.013
b) rs3128935 genotypes and age
Variables	Resolver N(%)	Chronic N(%)	OR (95% CI)
TT genotypes with ≥ 40 years	76 (30.8)	75 (34.4)	1.00
CT/CC genotypes with ≥ 40 years	22 (8.9)	24 (11.0)	1.09 (0.55–2.17)
TT genotypes with < 40 years	99 (40.2)	99 (45.4)	0.71 (0.41–1.25)
CT/CC genotypes with < 40 years	49 (20.0)	20 (9.2)	0.30 (0.14–0.61)
P for multiplicative interaction			P = 0.035

Logistic regression analyses adjusted for age, gender, high-risk population, and viral genotype.
