Effects of HIIT on different aetiology ILD
CTD-ILD, fibrosis, IPF, Fibrosis

Random-effect models were also created based on ILD type (clinical subgroups). We combined the IPF and CHP subgroups into the combined ‘Fibrosis’ clinical group. This was due to smaller numbers of IPF participants at the end of the study which did not allow for independent evaluation of this subgroup.The effects of HIIT on ILD of different aetiology were consistent with our primary analysis, that is, that HIIT peaked faster and the level of improvement was less. This result seemed to be largely attributable to the fibrosis group, which peaked fastest but showed the lowest improvement from baseline compared with the CTD-ILD group. Similar findings were observed for the other outcomes, again showing lack of preferential benefit from HIIT in any subgroup. While the CTD-ILD subgroup improved in most variables, the HIIT mode was not superior to MICT.
