Dose-response relationship between lung function and chest imaging response to silica exposures in artificial stone manufacturing workers

Table 5 Linear regression analysis for the association between cumulative respiratory silica exposure and lung function indices

	Cumulative RCS exposure (mg/m³ x year)			Weighted tenure (year)
	Coefficient	95% C.I.	P value	Coefficient	95% C.I.	P value
FVC, % of prediction	-0.46	(-0.88–0.05)	0.03	-0.11	(-0.29-0.07)	0.238
FEV1, % of prediction	-0.45	(-0.81–0.08)	0.018	-0.12	(-0.28-0.05)	0.155
FEV1/FVC, %	-0.006	(-0.24-0.23)	0.957	-0.03	(-0.13-0.07)	0.592

Models were adjusted for age, sex, body mass index, education, current smoking, ex-smoking, and cumulative smoking amount
