Adjusted odds ratio of the effect of the pandemic period on survival to hospital discharge in patients presenting in a shockable rhythm (VF/VT) with EMS attempted resuscitation.

	OR (95% CI)	p value
Pandemic period	0.50 (0.26−0.96)	0.037
Age (every year increase)	0.95 (0.94−0.97)	<0.001
Male gender	0.75 (0.40−1.40)	0.364
Call-to-patient time (every minute increase)	0.88 (0.82−0.94)	<0.001
Presumed cardiac aetiology	11.68 (1.19−114.88)	0.035
Public arrest location	2.17 (1.26−3.73)	0.005
Bystander witnessed	2.77 (1.42−5.41)	0.003
Bystander CPR	1.38 (0.61−3.09)	0.436
Who shocked first (reference PAD):
First Responder	0.54 (0.20−1.44)	0.217
Ambulance Victoria	0.54 (0.26−1.11)	0.094

OR = odds ratio; CI = confidence interval; CPR = cardiopulmonary resuscitation; PAD = Public Access Defibrillation.
