Age and disease history characteristics of ESRF patients discharged alive from ICU following an episode of critical illness and a comparator group of ESRF patients in the general population

	Cohort group (n = 111)	Comparator group (n = 440)	P value
Mean age (± SD)	59.3 (± 13.0)	58.6 (± 13.5)	0.59 (t)
Days on dialysis prior to admission or inclusion (median (IQR))	744 (222–2042)	915 (816–995)	0.31

ESRF = end-stage renal failure; ICU = intensive care unit; IQR = interquartile range; SD = standard deviation.
