Ninety-day mortality rate-adjusted covariables using Cox regression model and neurologic outcomes between the TTM and control groups.

Mortality-adjusted covariables using Cox regression model, n (%)				Relative risk (95% CI)	P value
TTM vs Control		32/87 (36.8)	34/54 (63.0)	0.39 (0.24–0.64)	< .001
Initial shockable rhythm vs initial non-shockable rhythm		30/88 (34.1)	36/53 (67.9)	0.36 (0.22–0.60)	< .001
CPR time ≤ 10 min vs > 10 min		17/50 (34.0)	49/91 (53.8)	0.53 (0.30–0.94)	.03
Age < 75 years vs ≥ 75 years		53/120 (44.2)	13/21 (61.9)	0.72 (0.39–1.35)	.31
Male vs female		51/112 (45.5)	15/29 (51.7)	1.00 (0.53–1.88)	1.00
CHD vs non-CHD		49/104 (47.1)	17/37 (45.9)	1.04 (0.58–1.86)	.91

Neurologic outcomes, n (%)		TTM (n = 87)	Control (n = 54)	Relative risk (95% CI)	P value
Poor neurologic outcomes		57 (65.5)	44 (81.5)	0.80 (0.66–0.98)	.04
CPC scores	1	19 (21.8)	6 (11.1)
	2	11 (12.6)	4 (7.4)
	3	8 (9.2)	3 (5.6)
	4	17 (19.5)	7 (13.0)
	5	32 (36.8)	34 (63.0)

CHD = coronary heart disease, CI = confidence interval, CPC = cerebral performance category, CPR = cardiopulmonary resuscitation, TTM = targeted temperature management.
