This article from the March 2015 issue of the European Respiratory Journal was published with an error in one sentence of the Methods section, in the subsection entitled “Pulmonary function tests”. Originally, the sentence erroneously stated that ΔXrs was calculated as the mean Rrs5 during inspiration minus the mean Rrs5 during expiration averaged over the sampling period. The correct sentence reads as follows:
“In addition, we report ΔXrs calculated as the mean Xrs5 during inspiration minus the mean Xrs5 during expiration averaged over the sampling period, a multiple-breath approach.”
The article has been corrected and republished online.
