CYP3A4 and infection: We found that Toll-Like Receptor 2 (TLR2), Interleukin 6 (IL6), CYP3A4, Solute Linking Carrier family 22 member 11 (SLC22A11) or Organic Anion Transporter 4 (OAT4), and ATP-Binding Cassette Subfamily C member 2 (ABCC2) polymorphisms were associated with the incidence of infection by themselves (Supplementary Table S1), and they were added to the final model.
