Table 5. Multivariate logistic regression analysis of PICU-acquired daily fluid overload and confounding variables associated with PICU mortality.

	AOR	95% CI	P
Agea	2.56b	1.12–5.88	0.026
MV	7.86	2.88–21.46	<0.001
PICU-acquired FOa	5.47c	1.15–25.96	0.032

AOR, adjusted odds ratio; CI, confidence interval; FO, fluid overload; MV, mechanical ventilation; PICU, pediatric intensive care unit. Variables of age, PIM2 score, AKI, ALI, Shock, DIC, MODS, change in antibiotics, and the use of MV, inotropes, and furosemide were entered into the multivariate logistic regression analysis with the backward method, as confounding factors. PICU-acquired daily fluid overload was coded as a continuous variable (n = 154).

^aData were log-transformed to fit model assumptions.

^bAOR represents the increase in odds per log increase in age.

^cAOR represents the increase in odds per log increase in FO.

The P value for the Hosmer-Lemeshow goodness-of-fit test was 0.507.
