Participant characteristics
The authors approached 1489 passers-by (718 men, 771 women). Of those, 600 committed to participate (40.30%), where two were excluded due to age under 18 (one from group B and one from group D). Nine dropped out of the study while reading the pamphlet but before the interview: eight because they could not provide the necessary time (two from group A, four from group B, one from group E and one from group F) and one because of insufficient Danish skills (one from group B). This left 589 for analysis. See the flowchart in Participants differed from the sampled non-participants: Participants were generally longer educated, younger and more often employed or studying.
