Table 4.

Incidence risk for acute kidney injury (AKI) and in-ICU mortality according to exposure to norepinephrine (NE)

Variables	Incidence risk (%)	OR (95% CI)	P-value
Before propensity score-weighted estimation
AKI,
NE exposure	21.0 [19.3 to 22.7]	4.74 (3.91 to 5.75)	< 0.001
In-ICU mortality, NE exposure	10.5 [9.2 to 11.8]	8.98 (6.34 to 12.73)	< 0.001
After propensity score-weighted estimation
AKI,
NE exposure	14.0 [13.5 to 15.5]	1.95 (1.63 to 2.34)	< 0.001
In-ICU mortality,
NE exposure	6.0 [5.0 to 7.0]	1.54 (1.19 to 1.99)	< 0.001

CI: confidence interval, OR: odds ratio, ICU: intensive care unit
