IL5 and HIV infectious disease: Notably the model had a better predictive performance compared to model 1 as it had three additional baseline covariates (sex partner having other partners, husband's income, age of the oldest sex partner) and seven individual difference cytokines (IL-2, IL-5, IL-16, CTACK, PDGF-BB, BNG-F and TRAIL) that were significant predictors of HIV infection.
