We follow our participants’ health by linking to their electronic medical records, which includes data on hospital stays, cancer diagnoses and causes of death.
These data enable researchers to know what health conditions participants are experiencing over time and when they were diagnosed. Combined with other data types, researchers around the world have been able to make health discoveries that would not otherwise have been possible.
