Comparison of clinical characteristics of patients in different diagnostic categoriesa
| Diagnostic category or parameter | No. (%) of males | Mean age, yr (SD) | Mean illness duration, wk (SD) | Mean hemoglobin level, g/dl (SD) | Median CD4 cell count/μl (IQR)b |
|---|---|---|---|---|---|
| Xpert blood positive | 9 (90) | 38.1 (1.5) | 3 (1.0–4.0) | 6.8 (0.7) | 54 (48–60) |
| PTB and Xpert blood negative | 22 (63) | 35.3 (2) | 4 (2.0–8.0) | 9 (0.4) | 89 (29–373) |
| Treated, unconfirmed TB | 21 (78) | 37.1 (1.6) | 4 (2.0–8.0) | 9.2 (0.5) | 108 (36–351) |
| Not TB | 17 (53) | 38.2 (2) | 2.5 (1.0–12.0) | 10.4 (0.5) | 152 (23–490) |
| P value | 0.11 | 0.71 | 0.82 | <0.001 | 0.09 |
a
Continuous parametric data (age, hemoglobin level, and duration of illness) were analyzed by ANOVA, continuous nonparametric data (CD4 cell count) were analyzed by Kruskal-Wallis test, and categorical data (gender) were analyzed by chi2 test.
