Univariate Cox regression analysis revealed the genotype AQP3 (−1431) GG genotypes as an independent risk factor for CMV infection, while risk in AA/AG allele is nearly halved with a hazard ratio of 0.526 (95% CI (0.32 to 0.866); p = 0.012; Table 5). This evidence concerns the gene AQP3 and cytomegalovirus infection.
