For IFN-γ, the association with CD4 count remained significant across most exclusions (β = –0.0010, 95% CI: –0.0018 to –0.0002, p = 0.021) but became non-significant when excluding the CD4 count × cysticercosis status interaction term (β = –0.0006, 95% CI: –0.0012 to 0.0000, p = 0.088). This evidence concerns the gene CD4 and cysticercosis.
