Hypertension was 10% (ARR 0.90; 95% CI 0.83, 0.98) lower in patients with CD4+ T-cell count < 350 cells/μL compared to those with CD4+ T-cell count ≥ 500 cells/μL. Similarly, patients with advanced WHO clinical disease stage had significantly lower risk of hypertension. Here, CD4 is linked to hypertensive disorder.
