From: Self-perceived quality of sleep among COPD patients in Greece: the SLEPICO study
Sleep outcome, measured by CASIS, based on the different therapeutic approaches, and adjusted to different ranges of CAT score. As we have established so far (see main text and previous figures), sleep outcomes in COPD patients correlate moderately with their age, TsD and disease severity stage, and strongly with the symptoms of the disease (estimated by CAT). For low CAT scores (0–10), treatment or no treatment does not seem to impact sleep outcomes. Nevertheless, for higher CAT scores (11 +), any treatment seems to notably improve sleep outcomes compared to no treatment. After adjusting for the CAT score, the use of ICS does not seem to impact sleep outcomes. CASIS100: COPD and Asthma Sleep Impact Scale, linearly transformed to a 0–100 scale, CAT: COPD assessment test, COPD: chronic obstructive pulmonary disease, ICS: inhaled corticosteroids, N: number of subjects, NT: no treatment, SD: standard deviation, T-ICS: COPD treatment scheme containing ICS, T-other: COPD treatment scheme not containing ICS.
