Data are presented as median (min–max), unless otherwise stated. The percentage of wrong responses was calculated on valid responses (i.e. after missing and “I don’t know” responses were excluded) and is the sum of two contributions. Wrong option: responses were considered wrong when a grade >0 was attributed to the wrong option in the questionnaire. All other options: responses were considered wrong when a grade = 0 was attributed to the other options in the questionnaire. The summary figure is reported in terms of median (minimum–maximum) of the percentages of wrong responses to each option.
