Thank you for showing interest in our article. The suggestion of the Bland-Altman plots is excellent. The plots provide more detailed information regarding patterns and magnitudes of disagreement than can be achieved with a single statistic such as the ICC. We included examination of Bland-Altman plots during our analyses, as indicated in our article. We did not include the plots in the published article because of space considerations (19 plots, 1 for each airway parameter) and because we thought that the addition of those 19 plots would take the reader’s focus away from the primary intent of the article.
