Smoking pack-years (yrs)	20.0 (10.0, 20.0)	20.0 (9.4, 21.25)	0.981^c
Years of occupational exposure to silica dust (yrs)			—
BMI			0.288^b
FVC (L)			0.676^b
FVC% pre			0.033^b
FEV1 (L)			0.145^b

BMI: body mass index; FEV₁: forced expiratory volume in 1 s; FVC: forced volume capacity; FVC% pre: FVC% predicted; FEV₁% pre: FEV1% predicted. Values are for normally distributed data or median (75th, 25th percentile) for nonnormally distributed data. ^aThe differences were calculated by the Chi-square test. ^bThe differences were calculated by Student’s -tests. ^cThe differences were calculated by the Mann-Whitney test.
