Our results showed that lower CD4 cell count <200 cells/μL (OR: 3.64, 95% CI: 2.9–4.58, p < 0.001), femaleness (OR: 2.9, 95% CI: 2–4.3, p < 0.001), WHO stage IV (OR: 2.11, 95% CI: 1.6–2.79, p < 0.001), coinfection with hepatitis B virus (HBV) (OR: 1.8, 95% CI: 1.18–2.71, p=0.01), BMI <18.5 kg/m2 (OR 1.4, 95% CI: 1.1–1.82, p=0.048), a viral load >100,000 (OR: 1.6, 95% CI: 1.28–2, p < 0.001), and age ≥40 years (OR: 1.55, 95% CI: 1.25–1.93, p < 0.001) were all risk factors of cytopenias (Figure 3(b); Table 3). The gene discussed is CD4; the disease is coinfection.
