“Functional ageing in fibrotic interstitial lung disease: the impact of frailty on adverse health outcomes.” Sabina A. Guler, Joanne M. Kwan, Janice M. Leung, Nasreen Khalil, Pearce G. Wilcox and Christopher J. Ryerson. Eur Respir J 2020; 55: 1900647.

Figures 1 and 2 in this article were published with the incorrect frailty index definitions for “frail” and “non-frail” subjects (in the key to the figures). Frail subjects were incorrectly defined as those with frailty index ≤0.21, and non-frail subjects with frailty index >0.21. The correct definitions of frail and non-frail subjects are those with frailty index >0.21 and ≤0.21, respectively, as presented in the amended figures below.
