This article from the January 2018 issue of the European Respiratory Journal was originally published with errors in figure 1. The numbers of subjects for each institute indicated in the box headed “Centre distribution” should have been
Dr Josep Trueta Hospital (n=37) and
Vall d'Hebron Hospital (n=7)
and in the box headed “Allocated to placebo (n=22)” should have been
Received allocated intervention (n=22)
Dr Josep Trueta Hospital (n=19) and
Vall d'Hebron Hospital (n=3)
The corrected figure is presented below, and the original article has been corrected and republished online. No further changes to the body text of the article were needed to address the error.
