Demographic characteristics at baseline.
obstructive defects
* n = 54, Ɨ n = 53BMI, body mass index; SD, standard deviationFor participants with PFT data (n = 54), 26.9% had obstructive defects (FEV1/FVC <80%) at baseline and 35.2% at 2 years (p = 0.012). A restrictive lung defect (TLC <80%) was present in 48.6% and 62.8% of participants at baseline and at 2 years (p = 0.049) respectively. Changes in PFT parameters from baseline to 2 years for the ACS and non-ACS groups were significant for a decline in FEV1 (p = 0.015) and FEF25-75% (p = 0.039) in the ACS group compared to the non-ACS group (
