Comparisons of the proportions of impairment in executive function and verbal fluency domains between controls and HIV+ patients.
| Test | HIV− (N = 395) | HIV+ (N = 347) | OR (95% CI) | P Value |
|---|---|---|---|---|
| Executive Function, impaired, N (%) | ||||
| Color Trails II Time | 46 (12.7%) | 87 (26.9%) | 2.53 (1.68, 3.85) | <0.001 |
| HCT Total Errors | 51 (14.4%) | 53 (17.2%) | 1.24 (0.80, 1.93) | 0.34 |
| Stroop Interference | 51 (14.1%) | 50 (15.8%) | 1.15 (0.73, 1.79) | 0.59 |
| WCST Total Errors | 53 (15.1%) | 79 (25.6%) | 1.94 (1.29, 2.92) | 0.001 |
| Executive Function Domain | 38 (12.0%) | 55 (20.2%) | 1.86 (1.16, 3.00) | 0.007 |
| Verbal Fluency, impaired, N (%) | ||||
| Category Fluency Trial 1 Words | 50 (13.7%) | 47 (14.6%) | 1.07 (0.68, 1.69) | 0.83 |
| Action Fluency | 51 (14.0%) | 79 (24.5%) | 1.99 (1.33, 3.01) | 0.001 |
| Letter Fluency | 47 (12.9%) | 54 (16.8%) | 1.36 (0.87, 2.13) | 0.16 |
| Verbal Fluency Domain | 47 (12.9%) | 76 (23.8%) | 2.10 (1.38, 3.21) | <0.001 |
Notes: OR, odds ratio, compares HIV+ to HIV−; CI, confidence interval; HCT, Halstead Category Test; WCST, Wisconsin Card Sorting Test; Impaired, domain deficit score > 0.5 or individual test deficit score >= 1.
