  1. FEV 1 forced expiratory volume in 1 second, FVC forced vital capacity, VC vital capacity,
  2. FEV 1/FVC (%) forced expiratory volume in 1 second.
  3. Values are presented as mean ± standard deviation.
  4. The regression coefficients for the individual mean annual changes in pulmonary function were calculated using simple linear regression analysis.
  5. Male versus female: Mann–Whitney U test, Kruskal-Wallis test.
