I. Participants with verified COPD (FEV1/FVC < 0.7 after bronchodilation) with severe resting hypoxemia (PaO2 < 7.4 kPa) when starting LTOT

Secondary analysis populations:

II. Participants with ILD as main reason for starting LTOT with severe hypoxemia (PaO2 < 7.4 kPa breathing air) at LTOT start

III. Participants with moderate hypoxemia (PaO2 7.4–8.0 kPa on air) at LTOT start by diagnosis and as a discrete group
