Cox proportional hazards model using all-cause mortality as an anchor with QLF with cut-off of week 24 changes
QLF changes in whole lung | Total patients (N=152) | Total deaths (n=11) (%) | HR (95% CI) | P value |
Continuous*, % | 1.20 (1.08, 1.34) | 0.001 | ||
Continuous*, mL | 1.01 (1.01, 1.02) | <0.001 |
Week 24 QLF changes in whole lung | Total patients meeting listed threshold, n (%) | Total deaths meeting listed threshold, n (%) | HR (95% CI) | P value |

Note: Mean change from previously modelled measurement variation of QLF of 0.4% (2.77×2×SD).
*The proportional hazards assumption is being examined and met using Schoenfield residuals.
