Gender differences can be found in pulmonary function and lung parenchyma
measurements. One fundamental question is: are these differences due to some biological
cause or simply due to size differences observed between the genders? Our research project
explores these differences to investigate whether size confounds the gender differences or
whether other biological variables may be at stake. The project uses propensity scores for
this exploration by matching males and females based on physical characteristics to
remove potential bias due to size, and assess gender differences in pulmonary function and
lung parenchyma on the matched subset.
