Long-term mortality and risk factors for development of end-stage renal disease in critically ill patients with and without chronic kidney disease

Table 7 Competing risks model for predicting risk of ESRD in 1-year ICU survivors by polynomial multivariable logistic regression analysis

Covariate	Relative risk ratio^a (95 % CI)	P value
Female gender	1.12(0.48–2.63)	0.787
Congestive heart failure	0.091 (0.011–0.690)	0.020
Admission serum potassium high (>4.59)	4.6 (1.30–16.40)	0.018
AKI	30.4 (5.98–154)	<0.001
CKD	265.7 (55.1–1280)	<0.001
AoC	356.6 (69.9–1811)	<0.001

Reference category = male, no comorbidity (according to Charlson index), admission potassium (3.9–4.59), no renal disease
