Table 5. Multivariate analysis of factors related to death.

Variable	Adjusted OR (CI 95%)	P value
Number of organ dysfunctions	1.52 (1.11–2.09)	0.009
Efficient RRT	0.41 (0.25–0.69)	< 0.001

Multiple logistic regression with variables adjusted for type of hospital, age, sex, smoking, number of comorbidities, lower tercile of platelets and higher creatinine at admission, use of vasoactive drugs, mechanical ventilation, and serum measurements (potassium < 5 mEq/ml, bicarbonate > 22 mEq/ml, urea > 150 mg/dl, and upper tercile of creatinine). OR: Odds ratio; RRT: Kidney replacement therapy.
