	Odds ratio (95% CI) for shockable rhythm (vs. non-shockable)
	Unadjusted	P value	Model 1*	P value	Model 2†	P value
Heart Failure sub-type

^*Adjusted for age, sex, and race/ethnicity.

^†Adjusted for age, sex, race/ethnicity, and comorbidities (obesity, diabetes, coronary artery disease, hypertension, hyperlipidemia, chronic obstructive pulmonary disease or asthma, chronic kidney disease, atrial fibrillation/flutter).

bHFpEF, heart failure with borderline preserved ejection fraction (>40% to <50%); HFpEF, heart failure with preserved ejection fraction (≥50%); HFrEF, heart failure with reduced ejection fraction (≤40%).
