	All	−3.23	−5.65	−0.82	<0.01
	Males	−4.17	−7.57	−0.77	0.02
	Females	−1.88	−5.41	1.64	0.29
	Walking speed
	All	−0.115	−0.202	−0.028	0.01
	Males	−0.136	−0.258	−0.013	0.03
	Females	−0.152	−0.300	−0.005	0.04

Grip strength in kg. Walking speed in ms⁻¹. Bold text indicates significance at level. Multiple linear regression adjusted for BMI, ultrafiltration volume remaining at time of scan (ml/kg dry weight), ethnicity, age, IMD quintile, Charlson index, self-reported health change, physical activity index (PAI) derived from GP physical activity questionnaire, [31, 32] use of walking aids (yes/no), EQVAS, and haemodialysis vintage (months).
