Tuberculosis (TB vs no TB) | Mean (95% CI) height-adjusted decline in FEV1 (ml/year) | Mean (95% CI) height-adjusted decline in FVC (ml/year) |
Model 1: Fully adjusted* (n=370) | 40.3 (25.4 to 55.1) | 42.7 (27.0 to 58.5) |
Model 2: Fully adjusted but excluding history of asthma, bronchitis or pneumonia (n=323) | 46.0 (30.8 to 61.1) | 46.9 (31.0 to 62.8) |
Model 3: Fully adjusted but excluding participants with previous TB (n=314) | 35.4 (19.4 to 51.4) | 42.3 (25.1 to 59.5) |
Model 4: Fully adjusted but excluding participants not meeting FEV1 or FVC reproducibility criterion (n=311) | 44.6 (29.9 to 60.2) | 47.0 (30.1 to 63.9) |
↵* Adjusted for lung function and silicosis at baseline and history of bronchitis, asthma or pneumonia, employment duration, current smoking (current vs past or never) and age at follow-up.
FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; TB, tuberculosis.
