Table 2 Assessment of CPR skills directly after training and at 6 months

From: The effect of a national web course “Help-Brain-Heart” as a supplemental learning tool before CPR training: a cluster randomised trial

  1. Results are presented as n (%) or mean (SD). Differences in proportions between groups were analysed with logistic regression within generalised estimation eqs. P values < 0.05 were considered statistically significant. NS, not significant. The table lists the variable’s best option at the top. All numbers are rounded to the nearest integer
  2. aDifferences in total score between intervention groups were analysed by mixed models linear test
  3. bUnpaired t test
