a Equivalent to absolute difference in mean FEV1 standardised
for height and age, compared with the general population. The reference
value for the general population is consequently 0.
b The 1997 general population data are
weighted according to the weighting scheme for that year's survey. Weighted
bases are not shown because they do not follow the 1999 weighting scheme.
