  1. a: Contains 1 missing data point in the RVR (−) group.
  2. Abbreviations: SNP, single nucleotide polymorphism; RVR, rapid virological response; OR, odds ratio; CI, confidence interval.
  3. Allele frequencies were determined by χ 2 test using 2 × 2 tables. Odds ratios and 95% CI per allele were estimated by unconditional logistic regression. P values less than 0.05 were considered statistically significant.
