Competing-risk models of variables associated with death and dialysis initiation (multivariate regression Cox and Fine & Gray models)

Outcomes	Predictive variables	Cox analysis		Fine & Gray analysis
		RR	CI	RR	CI
Death	Acute congestive heart failure	2.62	[1.17 - 5.89]	2.86	[1.31 - 6.26]
	Age (years)	1.09	[1.01 - 1.18]	1.09	[1.01 - 1.18]
	Walking impairment	2.11	[1.00 - 4.43]	2.17	[1.05 - 4.49]
	Hb <10 g/dL	3.73	[1.74 - 7.99]	3.85	[1.77 - 8.39]
Dialysis initiation	DBP (per cm Hg)	1.03	[0.99 - 1.07]	1.03	[1.01 - 1.06]
	eGFR <23 mL/min/1.73m2	12.95	[2.93 - 57.18]	13.37	[3.04 - 58.69]
	Hb <10 g/dL	0.49	[0.06 – 3.75]	0.32	[0.04 – 2.57]

RR=risk ratio, CI=confidence interval, Hb=haemoglobin, DBP=diastolic blood pressure, eGFR=estimated glomerular filtration rate.
