Ethics approval and consent to participate

: No new studies were conducted involving collection of data from individual people in order to conduct this modelling study. We relied entirely on administrative datasets, mostly already in the public domain, and on the published results of other studies. The BC government’s Liquor Distribution Branch provided data on outlet density and liquor sales by local areas of British Columbia which were used to model the effects of extreme changes to the density of liquor outlets on sales.

: There are no restrictions on the authors ability to publish this study. We received advance written consent from the funding body to prepare independent reports for publication in peer-reviewed journals. No individual-level data were used or reported in this study.

: A written statement was agreed between the co-authors and funding body at the outset of the project such that the implementation of the research from beginning to end would be arm’s-length and no Systembolaget staff would be involved in project meetings. A copy of the final report would be provided for comment on accuracy only in relation to descriptions of the organisation. An unconditional approval was also given for independent publication of any findings with the requirement only of being given a copy of a paper for information prior to its publication.
