Among participants who had initiated ART at enrollment, results from the longitudinal analyses demonstrate that participants with hookworm infection and participants without hookworm infection had a similar rate of CD4+ T cell immune recovery in the 24-months post-enrollment (βhookworm-time = 0.55; 95%CI: -0.35, 1.45; hookworm-time interaction term p-value = 0.23). The gene discussed is CD4; the disease is ancylostomiasis.
