Multiple logistic regression analysis for ROSC using K, F-T4, and growth hormone levels.

	Likelihood ratio test, p value	Odds ratio	Range
K (mEq/L)	0.0013∗	0.3208	0.1200–0.8572
F-T4 (ng/dL)	0.0023∗	1732.9	2.1465–1398992
GH (ng/mL)	0.0162	1.3261	0.9852–1.7848

Regression equation, p = 0.0004; ∗p < 0.05. ROSC, return of spontaneous circulation; K, potassium; F-T4, free T4; GH, growth hormone.
