Data are presented as arithmetic mean±sd, unless otherwise stated. Individuals with a valid FEV1 measurement at baseline are shown. For measures including FVC, only participants with both a valid FEV1 and FVC were included. Only workers that were included in the final analysis are shown (21 plants were included). FVC: forced vital capacity; FEV1: forced expiratory volume in 1 s. (For FEV1 % pred and FVC % pred the values are calculated as percentages of the European predicted values [23].) #: Asthma was defined as self-report of physician-diagnosed asthma; ¶: previous occupational exposure to dust or gases for more than a year.
