Mean Differences in Change Between the RIMT Group and Control Group at Short-Term, Medium-Term, and Long-Term Follow-upa
↵a The mean difference represents the intervention effect for the corresponding time period corrected for baseline value. For respiratory muscle strength, lung volumes and flows, and health-related quality of life, a significant positive mean difference presents a positive intervention effect. For perceived respiratory function, a negative mean difference presents a positive intervention effect. RIMT=resistive inspiratory muscle training, T0=baseline (measurements performed in the week before the start of the intervention period, T1=1 week after the intervention period, T2=8 weeks after T1, T3=1 year after discharge from inpatient rehabilitation, 95% CI=95% confidence interval, MIP=maximal inspiratory pressure, MEP=maximum expiratory pressure, FVC=forced vital capacity, FEV1=forced expiratory volume in 1 second, PEF=peak expiratory flow, MVV=maximum ventilation volume, PCF=peak cough flow.
