Table 4.

Clinical outcomes after propensity score matched by cardiac index between inotrope group and non-inotrope group.

	Inotropic (n = 359)	Non-inotropic (n = 359)	MD/OR [95%CI]	P-value
ARF, n (%)	120 (33.43)	102 (28.41)	1.27 [0.92, 1.74]	0.15
Ventilation LOS (days)	4.22 ± 5.60	4.04 ± 5.31	0.18 [−0.62, 0.98]	0.66
ICU mortality, n (%)	71 (19.78)	15 (4.18)	5.65 [3.17, 10.08]	<0.001
ICU LOS (hours)	180.16 ± 244.22	162.05 ± 233.43	18.11 [−16.84, 53.06]	0.31
Hospital mortality, n (%)	89 (24.79)	40 (11.14)	2.63 [1.75, 3.95]	<0.001
Hospital LOS (days)	13.77 ± 11.09	13.83 ± 11.80	−0.06 [−1.74, 1.62]	0.94

Data displayed as n (%) or mean ± standard deviation, and mean difference or odds ratio [95% confidence interval] with P-value for between-groups comparison using chi squared or analysis of variance. PSM, propensity score matching; ARF, acute renal failure; LOS, length of stay; MD, mean difference; OR, odds ratio; HR, hazard ratio; 95%CI, 95% confidence interval.
