Cardiac arrest	45.3 (0.0, 313)	7.1 (0.0, 74.4)	38.2 (− 293, 370)	0.3817
Death	21.1 (15.4, 26.9)	14.6 (11.2, 18.1)	6.5 (− 0.4, 13.4)	0.0644
Mechanical ventilation	6.3 (3.3, 9.2)	4.5 (3.3, 5.8)	1.7 (− 1.5, 5.0)	0.2915
Reintubation	5.1 (0.0, 10.6) (n = 18)	7.4 (1.6, 13.1) (n = 54)	− 2.3 (− 10.7, 6.1)	0.4877
