Age, disease history characteristics and APACHE II scores of ESRF patients with critical illness, comparing those who survived with those who died on the ICU

	ICU survivors (n = 111)	Died in ICU (n = 88)	P value
Mean age (± SD)	59.3 (± 12.9)	61.3 (± 13.6)	0.3
Median days on dialysis prior to admission (IQR)	744 (222 to 2042)	1139 (230 to 2028)	0.79
Mean APACHE II Score (± SD)	25 (± 5.7)	31 (± 8)	< 0.0001

APACHE = Acute Physiology and Chronic Health Evaluation; ESRF = end-stage renal failure; ICU = intensive care unit; IQR = interquartile range; SD = standard deviation.
