1
High quality CPR was based on arterial waveform data and defined as chest compression rate 90–130 compressions/minute, chest compression fraction ≥80%, and diastolic pressure ≥25 mmHg for age <1 year or ≥30 mmHg for age ≥1 year.
2
Fisher’s exact test.
3
Day is between 7:00 am to 11:00 pm. Weekday is Monday, starting from 7:00 am until Friday 11:00 pm. Weekend is after Friday 11 pm until Monday at 7:00 am.
4
Wilcoxon rank-sum test.
5
Characteristics by month are the number of months per unit of rolling refreshers.
