  1. aFollowing Fortnight 3, there was an excluded 2-week period for Study 1, when 230 ml glasses (rather than the 450 ml) were introduced to better match the glasses in the initial study on wine glass size (7), but these were withdrawn following customer complaints
  2. bDue to fidelity check violations (i.e. glasses not changed over on time), these periods lasted 3 weeks with establishments continuing to use this glass size for one extra week, although these additional weeks were not included in analyses
