On the other hand, Table 4 shows that low CD4+ count was significantly associated with a higher T. gondii seropositivity rate (61.9% vs. 27.3%), where patients with counts < 200 cells/μl were at more than fourfold higher risk of infection than those with counts ≥200 cells/μl (OR = 4.33; 95% CI = 1.617–11.610, P = 0.004). The gene discussed is CD4; the disease is infection.
