The SVR is 100% when both recipients and donors are CC genotype, 61% when donor is CC and recipient is non-CC, 39% when the recipient is CC and the donor non-CC and only 25% if neither donor nor recipient are CC genotype. Estimated odds ratio for Recipients, Non-CC: CC, adjusted for Donor IL28B genotype was 0.38, 95% CI 0.17–0.89, p=0.025. Estimated odds ratio for Donors, Not CC: CC, adjusted for Recipient IL-28 genotype was 0.16, 95% CI 0.068–0.366, p<0.001).
