The authors regret that in this paper predicting lung function decline we used change in best %pred FEV1 from baseline to follow-up as the outcome. In retrospect, we should have used an outcome measure that did not include baseline lung function values. As a result, this calls into question whether the median deviation from the best %pred FEV1 has the greatest predictive value for subsequent decline in lung function. Unfortunately, the data are not available to repeat the analysis to resolve this question. The authors would like to apologise for any inconvenience caused.
