Correction to: Respir Res (2021) 22:187 https://doi.org/10.1186/s12931-021-01773-1

The original version of this article unfortunately contained a mistake [1]. The minor correction of Table 1 was missing. That is, the text ‘FF’ should be ‘GFF’.

The correct Table 1 is given in this erratum.

Table 1 Demographic and baseline disease characteristics (mITT population)

The original article has been corrected.
