The CHSS Data Center conducts multi-institutional, longitudinal research. Study participants are enrolled at different institutions across the United States and Canada, and the information is sent to the CHSS Data Center, which is located at The Hospital for Sick Children (SickKids) in Toronto, Canada. The Data Center will send annual follow-up questionnaires to all study participants, even if the study has been closed to enrollment.
