CD4 and hypertensive disorder: In the multivariate adjusted Poisson regression model, the following factors were significantly associated (p<0.05) with a GFR <60 mL/min per 1.73 m2: age ≥50 years (PR = 3.4; 95% CI: 1.7–6.8), diabetes (PR = 2.0; 95% CI: 1.2–3.4), hypertension (PR = 2.0; 95% CI: 1.3–3.2), current CD4+ cell count <350 cells/mm3 (PR = 2.1; 95% CI: 1.3–3.3), and past exposure to TDF (PR = 4.7; 95% CI: 2.3–9.4) and IDV (PR = 1.7; 95% CI: 1.0–2.8).
