Kaplan–Meier curve analysis of the three MICA rs2596538 G/A genotypes confirmed the MICA rs2596538 GG donor genotype to be associated with a lower probability of CMV infection/disease compared to the MICA rs2596538 AA genotype (p = 0.0007; *p = 0.002; RH = 0.15; 95% CI 0.05–0.5; Figure S2 in Supplementary Material). Here, MICA is linked to cytomegalovirus infection.
