  1. Abbreviations: CI, confidence interval; HCV, hepatitis C virus; NR, no response; OR, odds ratio; RAF, risk allele frequency; SNP, single-nucleotide polymorphism; SVR, sustained virological response.
  2. Risk allele, the allele with higher frequency in cases compared with controls.
  3. Ptrend value was calculated by the Cochran–Armitage trend test with 100 000 permutations.
