Multiple logistic regression analysis for ROSC using K, F-T4, cortisol, and aldosterone levels.

	Likelihood ratio test, p value	Odds ratio	Range
K (mEq/L)	0.1268	0.6103	0.2584–1.1397
F-T4 (ng/dL)	0.0150∗	315.51	2.5538–432311
Cortisol (μg/dL)	0.4229	0.9618	0.8462–1.0710
Aldosterone (pg/mL)	0.1829	0.9982	0.9807–1.0005

Regression equation, p = 0.0040; ∗p < 0.05. ROSC, return of spontaneous circulation; K, potassium; F-T4, free T4.
