From: Development and validation of a prognostic score during tuberculosis treatment
Parameters | Values |
|---|---|
Linear predictor score (CABI), mean (standard deviation) | −2.89 (1.31) |
C-statistic by linear predictor score (CABI) (95% CI) | 0.812 (0.784–0.841) |
C-statistic by risk group | 0.788 (0.758–0.818) |
Mortality in each risk group | |
Class I, low risk, Total points < 46 | 16/1029 (1.6%) |
Class II, moderate risk, 46 ≤ Total points < 50 | 25/366 (6.8%) |
Class III, high risk , 50 ≤ Total points < 60 | 106/674 (15%) |
Class IV, critical risk , Total points ≥ 60 | 66/181 (36.5%) |
