Adjusted K-BILD total and domain scores
| IPF | SSc-ILD | P value | |
| Total score | 55.5 (51.9 to 59.1) | 62.6 (57.0 to 68.2) | 0.061 |
| Breathlessness | 41.5 (36.8 to 46.2) | 48.5 (41.3 to 55.7) | 0.141 |
| Chest symptoms | 66.2 (60.1 to 72.3) | 71.7 (62.5 to 81.0) | 0.362 |
| Psychological | 55.5 (50.2 to 60.8) | 71.9 (63.8 to 80.1) | 0.003* |
. Estimates are derived from analysis of covariance models, and represent the marginal mean K-BILD total or domain score at the mean value for each adjustment covariate (age, gender, FVC and DLCO). Presented as adjusted mean (95% CI).
*Remains significant after adjustment for multiple comparisons using the Bonferroni-Holm method (nominal p value 0.003 is less than the critical Bonferroni-Holm value of 0.0125).
DLCO, diffusing capacity of lung for carbon monoxide; FVC, forced vital capacity; ILD, interstitial lung disease; IPF, idiopathic pulmonary fibrosis; K-BILD, Kings Brief Interstitial Lung Disease; SSc, systemic sclerosis.
