Data expressed as n, mean (SD) or median (25th and 75th percentiles).
Data were analysed using independent t-tests (or Mann-Whitney U test for data that were not normally distributed) and χ2 test. All participants had data for each of the listed variables.
BMI, body mass index; CRQ, Chronic Respiratory Disease Questionnaire; GOLD, Global Initiative for Chronic Obstructive Pulmonary Disease guidelines; ISW, incremental shuttle walk; MRC, Medical Research Council dyspnoea score; PR-gym, pulmonary rehabilitation using specialist equipment; ; PR-min, pulmonary rehabilitation using minimal equipment.
