For untransformed variables, the data are expressed as mean (SD) (n); for geometric means the data are expressed as mean (95% confidence intervals) (n).

The total n value for various comparisons is not uniform because of missing data. The n value for a specific cell is listed in parentheses when it differed from the n value at the top of the column.

BMI, body mass index; FEV

_{1}, forced expiratory volume in 1 s; FVC, forced vital capacity.
