Associations of hypotension during first six hours post-cardiac arrest with outcomes. Hypotension defined as a minimum systolic blood pressure < 5^th percentile; percentiles derived from normative age and sex data.

	No hypotension	Hypotension	Unadjusted	Fully Adjusted^*	Parsimonious^**
	N (%)	N (%)	OR (95% CI); P	OR (95% CI); P	OR (95% CI); P
In-hospital mortality	70/169 (41)	114/214 (53)	1.61 (1.07, 2.43); 0.022	1.71 (1.02, 2.89); 0.042	1.71 (1.07, 2.76); 0.026
Unfavorable outcome	82/160 (51)	128/207 (62)	1.54 (1.02, 2.34); 0.043	1.83 (1.06, 3.19); 0.032	1.78 (1.08, 2.95); 0.024

OR, odds ratio; CI, confidence interval

Adjusted for age (cubic splines), pre-existing conditions (lung or airway; hematologic, oncologic, or immune compromised; genetic metabolic; neurologic), total number of vasopressors before arrest, night or weekend arrest, arrest location, first documented rhythm, and total doses of epinephrine at arrest; 26 patients removed due to missing data
