There was no association between PTB and COPD – those with previous PTB having a reduced FEV 1 :FVC (4.88% less than the norm), which was just short of significance ( p = 0.059).
The variables that remained included age, which reduced FEV1:FVC by 0.26% per year ( p = 0.015); current PTB, which reduced it by 6.44% ( p = 0.017); and previous PTB, which reduced it by 4.88% with a p -value approaching significance ( p = 0.059).
