Data are presented as n (%) except as noted.
*Reference category.
†Adjusted for age, sex, pack-years and years of asbestos exposure.
‡The changes were considered as mild if the radiological score was <2 and severe if the radiological score was ≥2.
§The calcification was considered as mild if it was sparse and high if a considerable part/nearly all of the pleural plaques were calcified.
