Filter Sets

Filter sets allow you to combine multiple filters into a single re-usable template, which can be used across multiple studies to ensure the same demographic requirements are applied.

These filters are then evaluated at study publish, with each study recruiting from the available pool of participants who satisfy the selected filters at that time.

Note that when publishing a duplicated study which used a filter set, it will use the filters applied to the filter set at the time it was applied to the original study. This can be updated by changing the filter_set_version on the study to the latest version, as returned on the filter set endpoint.
