Notes: Pre-announcement is January 2014-December 2015, interim is April 2016-March 2018, and post-implementation is April 2018-March 2019 (January-March 2016 excluded; see the methods section for details). Each row represents the change in the sugar content of non-alcoholic beverage purchases attributable to the corresponding decomposition factor. ‘Cross terms’ captures the cross terms correcting for simultaneous volume and sugar concentration changes.
