We appreciate the observations of Prof. Miller and colleagues about our article recently published in the International Journal of COPD.1 The authors feel that our conclusions are not supported by data, based on two main arguments.

The first is that concordant and discordant patients are different. This is obvious, and in fact, extensively detailed in our study. It seems that the authors erroneously suggest that our study is penalized by  election bias since concordant and discordant groups are quite dissimilar. In fact, we just compared two different ways of defining airway obstruction in the same prospective cohort, in a similar approach to that used by Prof. Miller et al in a previous publication.2
