The pulmonary function indexes in control and CB-exposed groups (mean ± SD)
| Variables | Control group (n = 104) | CB-exposed group (n = 81) | P -value |
|---|---|---|---|
| FEV1 (%) | 103.61 ± 14.52 | 98.07 ± 13.53 | 0.019a |
| FVC (%) | 104.67 ± 14.64 | 100.12 ± 13.47 | 0.071a |
| FEV1/FVC | 0.87 ± 0.05 | 0.84 ± 0.05 | 0.001a |
| PEF (%) | 93.76 ± 17.86 | 78.50 ± 16.80 | <0.001a |
| MMF (%) | 96.45 ± 23.18 | 86.86 ± 23.06 | 0.001a |
aTwo-sample t test. Differences were considered significant when P < 0.05. FVC%: percent predicted forced vital capacity, FEV1%: percent predicted forced expiratory volume in 1 second, MMF%: percent predicted maximal midexpiratory flow curve, and PEF%: percent predicted peak expiratory flow.
