Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Districts Which Implement Newer DA-BLS Training Program | the out of hospital cardiac arrest victims who were given bystander CPR by whom trained as newer dispatcher-assisted BLS training program, which more focuses on cooperation with a dispatcher, from recognition to perform DA-CPR and hands-on practice.~BLS CPR program with dispatcher assisted CPR simulation: the training program more focuses on cooperation with a dispatcher, from recognition to perform DA-CPR and hands-on practice. | 544 | 1,486 | OG000 | ClinicalTrials.gov |
| Group 2 | Districts Which Keep Traditional BLS Training Program | Control group commonly uses a one-hour training program which was developed by the Korea CDC. It focuses on detailed techniques of performing high-quality chest compressions. | 3,118 | 8,641 | OG001 | ClinicalTrials.gov |
