A logistic risk model that assumes a linear effect for moxifloxacin exposure
| Predictor variables | OR (95% CI) | p-value |
| Moxifloxacin exposure | 0.3 (0.1–0.9) | 0.03 |
| Fluoroquinolones other than allocated moxifloxacin | 2.6 (0.4–17.3) | 0.33 |
| Male | 2.1 (0.4–11.7) | 0.41 |
| Age yrs | 0.97 (0.93–1.01) | 0.16 |
| History of drinking | 2.8 (0.5–15.8) | 0.24 |
| Past TB treatment | 0.6 (0.1–2.4) | 0.43 |
| History of bronchiectasis | 0.4 (0.1–2.1) | 0.30 |
| Symptomatic on presentation | 0.1 (0.0–0.5) | 0.01 |
| Cavitation on initial chest radiograph | 4.0 (0.5–34.8) | 0.22 |
| Extent of disease greater than equivalent of right upper lobe on chest radiograph | 29.5 (4.3–203.1) | <0.001 |
History of smoking has been excluded owing to significant correlation with males. TB: tuberculosis.
