In most studies, researchers set quotas for precise demographic and HCP specialty groups, or even additional criteria, to ensure a representative sample. When the number of participants who meet a specific criterion reaches its predetermined limit, that quota is considered full, and further responses from this specific group are no longer accepted. Unfortunately, due to high demand for participation in certain studies, there may be cases where this sufficiency of responses is not displayed immediately, but rather after the responses have been submitted. 

We always recommend our esteemed panelists to access studies as soon as possible to avoid receiving “Quota Full” survey results.
