Two cohorts were used (n=613) with eligibility criteria of a clinical diagnosis of COPD, an FEV1/FVC <70% and an ISWT (after familiarisation) before and after a 7-week course of pulmonary rehabilitation (PR). The MID of the ISWT using the distribution method was 36.1 m. The area under the curve to discriminate between perceived 'improvement' and 'no improvement' after PR for a change in ISWT of 35 m was 0.66 (0.58-0.73). The MID of the ISWT is therefore between 35.0 and 36.1 m. %I University of Leicester
