	Coefficient	OR (95% CI)	p
Intercept	-3.786		<0.0001
Male sex	1.050	2.86 (2.16 to 3.77)	<0.0001
CKD stage > =3B	0.717	2.05 (1.47 to 2.84)	<0.0001
Age 65 - 85	0.981	2.67 (1.29 to 6.48)	0.0159
Age >85	1.801	6.05 (2.94 to 14.66)	<0.0001
AMTS <7	0.505	1.66 (1.26 to 2.17)	0.0002
AKI during admission	1.008	2.74 (2.09 to 3.59)	<0.0001
Two or more comorbidities	0.383	1.47 (1.11 to 1.93)	0.0067

Patients with no known baseline eGFR were assigned to CKD Stage 2. The results for all predictors are almost identical if age is used as a continuous variable (OR 1.069 (1.051 to 1.087); p <0.0001)

AKI Acute Kidney Injury

eGFR estimated glomerular filtration rate

CKD Chronic kidney disease

AMTS Abbreviated mental test score
