  1. aHighest sustained viral response. bCausal haplotype; lowest sustained viral response. cSNPs currently used for genotyping to decide CHC treatment. Odds ratio (OR) and percentage of haplotypes in chronic hepatitis C (CHC) in patients of European descent (CEU) are from Smith et al. [20]. CI, confidence interval.
