  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)
