Table 3 Total scores for the questionnaire directly after training and after 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

 

CPR training only, directly after (n = 587)

Web course + CPR training, directly after (n = 645)

  1. The results are presented as the means (SD). P values < 0.05 were considered statistically significant. Theoretical knowledge resulted in a total score of 0–7 points for stroke symptoms, 0–9 points for AMI symptoms and 0–6 points on lifestyle factors
  2. aDifferences in total score between intervention groups were analysed by mixed models linear test
  3. bUnpaired t test
