Results are presented as n (%) or mean (SD). Differences in proportions between groups were analysed by Pearson's χ2 test. Differences in total score between intervention groups were analysed by mixed models linear test* and unpaired t-test†. p Values<0.05 were considered statistically significant. All numbers are rounded to the nearest whole number. CPR, cardiopulmonary resuscitation; NS, not significant.
