Change in ISWT distance differed across GCRS categories (p&lt;0.05); participants reporting slight improvement increased ISWT distance by 60.7\u00b185.9\u2009m. Receiver operating characteristic analysis identified an optimal cut-off of 35\u2009m (area under the curve 0.70, 95%\u2009CI 0.61 to 0.79; p&lt;0.05).
