Data are shown as medians (range), except sex. Normal reference ranges are given in square brackets. values were determined by logistic regression analysis, except for sex (chi-squared test). < 0.05. ROSC, return of spontaneous circulation; Na, sodium; K, potassium; TSH, thyroid stimulating hormone; F-T3, free T3; F-T4, free T4; ACTH, adrenocorticotrophic hormone; GH, growth hormone; IGF-1, insulin-like growth factor-1; PRA, plasma renin activity.
