Table 4 Association between the objective measures of physical function and PROMIS

Physical measures	Depression		Physical function		Pain interference		Fatigue		participation in social roles and activities
Physical measures	F-value	p	F-value	p	F-value	p	F-value	p	F-value	p
Quadriceps force (N)	/	NS	10.96	< 0.001	/	NS	4.83	0.03	/	NS

R square values are based on a general linear model; factors introduced to the model included absolute quadriceps and handgrip force, Sit-to-Stand test, 6MWT, Tinetti and the dialysis fall index. Abbreviations: 6MWT six-minute walking test, DFRI dialysis fall risk index
