When you participate in a study, your study center will inform you of the number of visits required to complete the study. One or several visits during a period of a few days to several months can be required. This will depend on the characteristics of the study that you’re participating in. You may also receive financial compensation for your participation in a study, based on the number of visits and other inconveniences associated with the visits.
