|---|---|---|---|---|---|
| Positive | Negative | ||||
| 0 | – | – | – | – | – |
| 1 | 100 (83–100) | 67 (48–82) | 65 (45–81) | 100 (85–100) | 79 (66–89) |
| 2 | 75 (51–91) | 91 (76–98) | 83 (59–96) | 86 (70–95) | 85 (72–93) |

Data presented as median % (interquartile range). The ICU TB score (values from 0 to 3) is based on the sum of three parameters: military tuberculosis (yes = 1; no = 0), required mechanical ventilation on ICU admission (yes = 1; no = 0) and required vasopressor infusion (yes = 1; no = 0).
