Longitudinal analysis of rates of absolute change in FEV1% predicted and BMI by travel time.

Absolute change in	One-way travel time by automobile to SPH, min
	<45 ()	45–150 ()	150–360 ()	>360 ()
FEV1 % predicted/year	−0.9 [−1.6, 0.1]	−0.5 [−1.8, 0.8]	0.1 [−1.0, 1.2]	−3.1 [−5.1, −1.1]
BMI (kg/m^2)/year	0.0 [−0.1, 0.1]	0.1 [−0.2, 0.3]	0.3^£ [0.1, 0.5]	−0.3 [−0.6, 0.1]

Mean [95% confidence interval].
FEV1: forced expiratory volume in 1 second; BMI: body mass index.
⁢ in comparison to reference group (one-way driving travel time < 45 mins).
^£ in comparison to reference group (one-way driving travel time < 45 mins).
The remainder of the comparisons was not statistically significant.
