Comparison of outcome measures between peer-led group and professional-led group
| Chest compression | Peer-led group | Professional-led group | Difference of means (95% CI) or P value* |
|---|---|---|---|
| Compression depth (mm) | 43.5 ± 7.6 | 42.8 ± 9.5 | 0.75 (−4.5 to 6.0) |
| Percent compression with adequate depth (38–51 mm) (%) | 54.5 ± 31.9 | 52.5 ± 35.6 | 2.0 (−18.7 to 22.8) |
| Proportion of participants with adequate compression depth, n (%) | 16/23 (69.6) | 12/22 (54.5) | P = 0.299 |
| Compression rate (per minute) | 104.3 ± 9.1 | 109.6 ± 10.6 | −5.3 (−14.4 to 3.7) |
| Proportion of participants with adequate compression rate (90–110/minute), n (%) | 17/23 (73.9) | 8/22 (36.4) | P = 0.011 |
| Questionnaire scores | |||
| I mmediately after BLS training | 18.2 ± 1.4 | 18.0 ± 1.7 | 0.27 (−0.45 to 0.99) |
| At 20 weeks after BLS training | 17.2 ± 2.3 | 17.8 ± 2.0 | −0.57 (−1.72 to 0.57) |
