Table 2. Unadjusted Risk of Outcomes with Exposures.

The unadjusted risks of primary and secondary outcomes were calculated in the presence of left ventricular dysfunction (LVD), right ventricular dysfunction (RVD), severe pulmonary hypertension (PH), all three exposures, or none of the exposures. Shown are risks and their 95% confidence interval. ECMO: extracorporeal membrane oxygenation.

Exposure	Composite Outcome	Death	ECMO Utilization
LVD
Yes	52.0% (40.6%, 63.5%)	6.8% (1.0%, 12.6%)	30.1% (19.6%, 40.7%)
No	17.6% (14.6%, 20.7%)	2.0% (0.9%, 3.1%)	6.7% (4.7%, 8.6%)
RVD
Yes	42.3% (34.1%, 50.6%)	6.6% (2.4%, 10.7%)	20.4% (13.7%, 27.2%)
No	16.6% (13.4%, 19.8%)	1.9% (0.7%, 3.0%)	6.4% (4.3%, 8.5%)
Severe PH
Yes	31.1% (26.6%, 35.6%)	3.9% (2.0%, 5.8%)	14.2% (10.8%, 17.6%)
No	7.0% (4.1%, 9.8%)	0.3% (0.0%, 1.0%)	1.7% (0.2%, 3.1%)
LVD + RVD + Severe PH
All	61.5% (46.3%, 76.8%)	7.7% (0.0%, 16.1%)	35.9% (20.8%, 51.0%)
None	6.5% (3.3%, 9.6%)	0.4% (0.0%, 1.3%)	1.3% (0.0%, 2.8%)
