SGRQ-Ider total score (mean and 95% confidence intervals) in A the lower and upper quartile of 6MWD, B the lower and upper quartile of FVC % predicted, C the lower and upper quartile of DLCO % predicted, D LTOT, and E GAP index. SGRQ-Ider: IPF-specific version of the St. George’s Respiratory Questionnaire derived from results from the original St. George’s Respiratory Questionnaire; 6MWD: distance walked during the 6-min walk test; FVC: Forced vital capacity; DLCO: Diffusing capacity of the lung for carbon monoxide; LTOT: Long-term oxygen therapy; GAP: Gender, age and physiology index
