  1. aPositive responses are recoded from the variables “definitely yes” and “probably yes”
  2. bThe McNemar test was used for the analysis of these two dependent categorical variables
  3. CC + MMV chest compressions and mouth-to-mouth ventilation, CC + PMV chest compressions and mask-to-mouth ventilation
