Nevertheless, we performed a subanalysis according to the type of organ transplanted (Supplementary Tables S1, S2) and found that kidney and liver recipients presenting with TLR4 rs4986790/rs4986791 polymorphism presented more frequently CMV infection comparing with those with wild type (70% vs 41% and 100% vs 51% respectively, p=0.05). Here, TLR4 is linked to cytomegalovirus infection.
