Baseline assessment
visual or manual dexterity impairment
Baseline assessments of all study participants took place before and during one of their usual dialysis sessions. To negate the potential effect of the long break from dialysis upon frailty measurements, we avoided the first haemodialysis session after the weekend interval. Where participants dialysed twice weekly, the dialysis session after the shortest interval was chosen for baseline assessment.Study participants completed a number of investigations, which are detailed in our methodology paper [A full description of frailty tool components is contained in As some participants had visual or manual dexterity impairment, abridged versions of MoCA were also permitted, by omitting executive function and naming sections for visually impaired, and the executive function section only for those lacking dexterity to draw [
