Changes in pulmonary function tests in the follow-up study

Values Males Females
Patients n 181 107 74
FVC −0.47 ± 1.2 −0.49 ± 1.3 −0.45 ± 0.87
DL,CO −0.72 ± 1.4 −0.78 ± 1.8 −0.70 ± 1.5
KCO −0.2 ± 0.9 −0.27 ± 0.8 −0.18 ± 1.1
PA–a,O2 mmHg 0.19 ± 0.9 0.32 ± 0.8 0.12 ± 0.6

Unless otherwise stated, data are presented as the mean ± sd percentage of change in absolute values or difference in pressure (mmHg) with respect to initial assessment, divided by the length of follow-up in months. FVC: forced vital capacity; DL,CO: diffusion capacity of the lung for carbon monoxide; KCO: ratio between DL,CO and alveolar volume; PA–a,O2: alveolar arterial oxygen tension difference. 1 mmHg=0.133 kPa.
