6MWT, six minute walk test distance (metres); CI, confidence interval; MCS, mental component summary; PCS, physical component summary; PF, physical functioning
^aEffect size = mean change from baseline/standard deviation at baseline
^bEffect size = (Intervention mean change-Control mean change)/ pooled standard deviation for change
^cNorm-based score for Australian normative population mean = 50, standard deviation = 10.
