Randomisation and blinding
hypersensitivity, Allergic Alveolitis, IPF, CTD-ILD
HYPERSENSITIVITY, ALLERGIC ALVEOLITIS
Following baseline assessments, participants were randomised into two groups: exercise using MICT (MICT group) or exercise using HIIT (HIIT group). Participants were stratified by ILD type to ensure a balanced distribution of types between groups. They were placed into three subgroups: (1) idiopathic group (eg, IPF); (2) autoimmune group (connective tissue disease-related interstitial lung disease (CTD-ILD)) and (3) chronic hypersensitivity pneumonitis/Extrinsic Allergic Alveolitis group (CHP/EAA). The investigator performing all assessments and the statistician were blinded throughout the study.
