The period from the launch of the Sport-Santé website (April 22, 2015) to July 5, 2015 was excluded from the analysis. The period from July 5, 2015 to September 5, 2015 was considered as a control period. The effect of the advertising on the number of visits to the website was tested from September 5, 2015 to May 25, 2016 (testing period). The articles and the booths which promote Sport-Santé are identified by crosses and circles, respectively.
