Table 2 Change in lung function with exercise with interaction term analyses (Subjects ≥ 10 years old)
From: Self-reported exercise and longitudinal outcomes in cystic fibrosis: a retrospective cohort study
Models: n = 389 subjects | Estimated FEV1% at time = 0 without exercise* | Estimated FEV1% at time = 0 with exercise* (pvalue) | Baseline Change in FEV1% per year (pvalue) | Change in FEV1% over baseline per year with exercise (pvalue) | Change in FEV1% over baseline per year for interaction (pvalue) | |
