Declarations

:

: Gamblers were informed of, and consented to, personal and gambling data collection and analysis in the general conditions of use when opening an account on the website. The PMU ensures compliance with data protection regulations by adhering to the General Data Protection Regulation (GDPR) No. 2016/679 of April 27, 2016, and the amended French Data Protection Act of January 6, 1978. These measures guarantee the secure handling and protection of personal data throughout its operations and allow the analysis of the routinely recorded data for public health purposes. The study obtained local IRB approval of Nimes Hospital n° 25.01.03. The approval included the fact that the participants were not aware that they were randomly assigned to one of two conditions, nor gave consent to participate since PMU implemented the optimized versus standard procedure testing as part of their ordinary operations. The study was prospectively registered on clinicaltrials.gov under the identifier NCT05413564.

: Not applicable.

: AL signed a data sharing agreement for the "OSE" study, through an academic-private convention with the FDJ and for a previous study with Winamax. Independency of the research with no constraint on the protocol, the analysis and the publication were guaranteed by a strict convention between the hospital and the FDJ/Winamax, and no funding was part of the conventions.
