Authors' conclusion
We observed a persisting wide variability in OHCA characteristics and outcomes across registries and the potential impact of the COVID-19 pandemic within registries.

Further findings
Survival and favourable neurological outcome, COVID-19 pandemic period · 2020-2021 vs 2018-2019
- Lower in 2020-2021 COVID-19 pandemic period than 2018-2019 in the majority of registries
