Virological suppression by diagnostic group, restricted to patients with viral-load data (n = 406)
| Diagnostic group | Patients, n | VL available, n (%) | Suppressed < 1,000 c/mL, n (% of available, 95% CI) | VL < 200 c/mL, n (%) |
|---|---|---|---|---|
| Major depressive disorder | 138 | 119 (86.2) | 101 (84.9; 77.4–90.2) | --- |
| Opportunistic CNS infection | 206 | 105 (51.0) | 80 (76.2; 67.2–83.3) | --- |
| HIV-attributed/organic CNS | 148 | 113 (76.4) | 94 (83.2; 75.2–89.0) | --- |
| Bipolar spectrum disorder | 40 | 33 (82.5) | 29 (87.9; 72.7–95.2) | --- |
| Psychosis spectrum | 12 | 9 (75.0) | 5 (55.6; 26.7–81.1) | --- |
| Dementia spectrum | 15 | 9 (60.0) | 9 (100.0; 70.1–100) | --- |
| Anxiety / stress-related | 17 | 14 (82.4) | 13 (92.9; 68.5–98.7) | --- |
| Overall | 581 | 406 (69.9) | 335 (82.5; 78.5–85.9) | --- |
VL viral load, c/mL copies/mL, CI Wilson confidence interval. Suppression uses the WHO threshold (< 1,000 c/mL). Wide intervals for small groups (notably psychosis, dementia and substance use) indicate that group-level differences are imprecise and hypothesis-generating. Substance use disorder (3 with VL) and other neurological/medical (1 with VL) omitted owing to very small denominators
