Odds Ratios of In‐Hospital, 7‐Day, and 30‐Day Mortality in Patients With AMI‐CS Managed With VA‐ECMO Plus IABP Compared With VA‐ECMO Alone

	In‐hospital mortality	7‐day mortality	30‐day mortality
Univariable	0.42 (0.34–0.52)	0.28 (0.23–0.33)	0.37 (0.30–0.46)
Multivariable
Model 1	0.47 (0.38–0.59)	0.30 (0.25–0.37)	0.41 (0.33–0.51)
Model 2	0.47 (0.38–0.59)	0.30 (0.25–0.37)	0.41 (0.33–0.51)
Model 3	0.47 (0.37–0.59)	0.30 (0.25–0.36)	0.40 (0.33–0.50)
PSM	0.48 (0.37–0.63)	0.28 (0.22–0.36)	0.43 (0.33–0.56)
IPTW	0.42 (0.34–0.52)	0.28 (0.23–0.33)	0.37 (0.30–0.46)

Values are expressed as odds ratio (95% CI). The following variables were used for the multivariable adjustment: Model 1 included age category, sex, full score Barthel index at admission, Killip classification, comorbidities, cardiac arrest at admission, and hospital characteristics; model 2 included age category, sex, full score Barthel index at admission, Killip classification, cardiac arrest at admission, and hospital characteristics; and model 3 included age category, sex, full score Barthel index at admission, Killip classification, comorbidities, and cardiac arrest on admission. AMI‐CS indicates acute myocardial infarction complicated by cardiogenic shock; ECMO, extracorporeal membrane oxygenation; IABP, intra‐aortic balloon pumping; IPTW, inverse probability of treatment weighting; PSM, propensity score matching; and VA, veno‐arterial.
