Pulmonary function parameters (observed values-predicted values (SD)) in males (n = 196) and females (n = 43) stratified by exposure duration
| Male | Female | |||||||
|---|---|---|---|---|---|---|---|---|
| n = 196 | FCV (ml (SD)) | FEV1 (ml (SD)) | FEV1/FCV (% (SD)) | n = 43 | FCV (ml (SD)) | FEV1 (ml (SD)) | FEV1/FCV (% (SD)) | |

| †Adjusted for smoking. | ||||||||
| FVC, forced vital capacity; FEV1, forced expiratory volume in one second. | ||||||||
| Group definition: non-exposed group: exposure duration in the food industry = 0; duration 1 = exposure duration in the food industry ⩽6 years; duration 2 = exposure duration in the food industry >6 years. | ||||||||
