Kaplan–Meier curves indicated that MICA-129 mismatch status (recipient Met/Met and donor Met/Val or Val/Val) conferred shorter cytomegalovirus-infection-free survival (p = 0.004; Figure 1A) and kidney-rejection-free survival rates (p = 0.007; Figure 1B) during the first year post-SPKT. This evidence concerns the gene MICA and infection.
