Risk factors for acute kidney injury (AKI):
(1) severity of CO poisoning (severe aHR 3.8; mild or moderate aHR 2.2; reference without CO poisoning)
(2) older age (>= 50 years aHR 5; 35 to 49 years aHR 1.7)
(3) male sex (aHR 2)
(4) diabetes (aHR 2.2)
(5) hypertension (aHR 2.3)
(6) hyperlipidemia (aHR 1.8)
