^a A passing score for the children was 13 or more correct answers out of 24 questions, and a mastery score was 20 or more correct answers out of 24 questions. A passing score for the parents was11 or more correct answers out of 18 questions, and a mastery score was 15 or more correct answers out of 18 questions
^b10,183 children completed the first test at the end of the term when the lessons were taught in the Informed Health Choices (IHC) primary school trial [44], and 6787 completed the second test after 1 year [45]. There were 561 parents who completed the first test in the IHC podcast trial after listening to the podcast and 523 completed the second test after 1 year
^cThe intervention in the IHC primary school trial included a workshop for the teachers, a textbook, exercise book, teacher’s guide, and nine 80-min lessons with reading, exercises and classroom activities. The differences are adjusted for stratification variables in both studies. The differences for the passing and mastery scores are based on the adjusted odds ratios, using the control groups as the reference
^dThe test scores in the intervention group after 1 year relative to the test scores shortly after the intervention in the intervention group. Retention for the mean score is adjusted for chance. There was a probability of the children answering 39% of the questions correctly by chance and of the parents answering 37% of the questions correctly by chance
