Table 2.

The comparison of pulmonary function parameters of the exposed and non-exposed groups.

Parameters	Exposed group^∗∗ (mean ± SD)	Non-exposed group (mean ± SD)	p-value^∗
FVC	93.22 ± 7.47^†	96.52 ± 7.18	<0.001
FEV1	91.65 ± 8.05^†	96.99 ± 8.03	<0.001
FEV1/FVC	98.46 ± 6.28^†	100.62 ± 6.81	0.001
PEF	98.39 ± 9.41^†	101 ± 10.77	0.001

^∗

Independent Samples t-test.

^∗∗

Data of the last year of the study (2019).

^†

Significantly different from its corresponding values for the non-exposed group. FVC: forced vital capacity; FEV1: forced expiratory volume in the first second; PEF: peak expiratory flow.
