RVR: Rapid virological response. EVR: Early virological response. SVR: Sustained virological response. OR: Odds ratio. CI: confidence interval.

Odds ratio in the different genotypes are referred to the genotype with OR = 1. The value “0” means that there were no subjects carrying this genotype.

Note: the remaining genetic variants assessed showed no significant associations with RVR, EVR and SVR (p>0.05 for all comparisons).
