Fig 2. Improvement in children’s knowledge pre- musical and two weeks post-musical.

Impact of musical on knowledge in primary school children (n = 161) using a generalised linear model accounting for confounding factors of prior knowledge, exposure to antibiotics, school year and school attended. Prior knowledge of AMR was a significant confounding factor in questions “Antibiotic resistant infections can be life-threatening”, “Infections can only get better if treated with antibiotics” and “If I get a headache and runny nose I will definitely need antibiotics”. School attended was a significant confounder in questions “The number of antibiotic resistant infections in the world is increased by careful, prudent use of antibiotics”, “Antibiotics are essential for treating serious bacterial infections” and “If I get a headache and runny nose I will definitely need antibiotics”.
