Data expressed as mean (95% CI) or median (25th and 75th percentiles) pre-to-post PR.
Data were analysed using independent t-tests (or Mann-Whitney U test for data that were not normally distributed). All participants had data for each of the listed variables.
CRQ, Chronic Respiratory Disease Questionnaire; ISW, incremental shuttle walk; PR, pulmonary rehabilitation; PR-gym, pulmonary rehabilitation using specialist equipment; PR-min, pulmonary rehabilitation using minimal equipment.
