  1. Values are median (interquartile range). Participants were grouped based on whether they used arms to chair-stand or used a walking-aid at both timepoints (‘aided’), neither timepoint (‘unaided’), at baseline but not follow-up (‘aided at baseline only’), or at follow-up but not baseline (‘aided at follow-up only’). a The amount of time between baseline and follow-up assessments was calculated for all completers of Staying Steady. Sub-analyses of primary outcome measures were performed following removal of participants from the first and tenth decile, for the amount of time between assessments. Primary outcome data from all completers are shown in the right-hand column for direct comparison. **P < 0.01 between baseline and follow-up
