Table 1.

Return of spontaneous circulation (ROSC) and 1-month survival rate after CPA with or without adrenaline administration

ROSC
(n = 8,136)		 Non ROSC
(n = 104,302)		 1-month survival rate after CPA
(n = 5,907)		 Non survival
(n = 106,538)
Adrenaline administration 1,570 (18.5%)*** 6,651 (81.5%) 427 (5.2%) 7,737 (94.8%)
No adrenaline administration 6,566 (6.3%) 97,691 (93.7%) 5,480 (5.3%) 98,801 (94.7%)

ROSC and 1-month survival rate after CPA for adrenaline administration were compared using the chi-square test.

The rate of ROSC was significantly higher in the group with adrenaline administration compared to the group without adrenaline administration; however, there was no difference in the 1-month survival rate. ***p < 0.001 in chi-square test.
