Thus, the model, including genetic and non-genetic variables, is:ln(p1−p)=3.47×(TLR2 TT)− 13.9×(IL6 GG)5.4×(OAT4 AT)−10.5 × (OAT4 TT)+  2.8×(ABCC2 GG)+ 11.1×(CYP3A4 CC)−1.1×(Cycle)−2.4×(Male sex)+3.4 × (From 18 to 40 years)+9.4×(From 41 to 60 years)+0.2 × (Induction)+4.6×(AML)+1.3×(Other leukemias)+9.6×(Lymphoma)+0.5 × (Days in deep neutropenia)−1.9where p is the probability of occurrence of infection, with values ranging from 0 to 1 (or 0%–100% of occurrence probability). The gene discussed is CYP3A4; the disease is infection.
