Data are presented as mean±sd
Statistical comparisons: values at the time of maximum impairment (i.e. 3 months) and values at 12 months and 5 yrs after BMT are compared with values pre-BMT
FVC: forced vital capacity
% pred: per cent predicted
FEV1: forced expiratory volume in one second
TL,CO: transfer factor of the lung for carbon monoxide
TL,CO-Hb: transfer factor of the lung for carbon monoxide corrected for haemoglobin level
Hb: haemoglobin
*: p<0.05
***: p<0.001, Bonferroni's correction for multiple comparisons
