Table 2 Numbers and proportions of correct answers for primary and secondary outcomes

From: Assessment of breathing in cardiac arrest: a randomised controlled trial of three teaching methods among laypersons

  Correct answers/number of answers (%)

 No breathing
  Lecture 139/156 (89%)
  Video 137/150 (91%)
  Simulation 138/153 (90%)
 Agonal breathing

  Simulation 143/153 (93%)
  1. Total number and proportions of correct answers for primary outcome (recognition of breathing patterns) and secondary outcomes (recognition of each breathing pattern). Numbers are calculated as the total number of correct answers (for example, 52 participants were randomised to receive lecture-based teaching and watched a total of 9 videos for the primary outcome providing the possibility of 468 correct answers)
