Design outcomes

Primary

Measure	Time frame
The primary outcome is the difference in FVC between measurements in the morning and afternoon	—

Secondary

Measure	Time frame
- Difference in Forced Expiratory Volume in 1 second (FEV1) between measurements in the morning and afternoon. - Difference in Peak Expiratory Flow (PEF) between measurements in the morning and afternoon. - Difference in HRQOL at baseline and after 6 weeks measured by K-BILD. - Exploratory comparison of the differences in change in FVC between different fibrotic interstitial lung diseases. - Difference in activity (steps) between morning and afternoon	—
