Data Harmonization

The CPTP datasets are generated using a rigorous harmonization process achieved in collaboration with Maelstrom Research. To learn about the harmonization methods and software used to harmonize data across the CPTP cohorts, click here.

CPTP harmonized data comprise information from several sources: Health and Risk Factor Questionnaires, including medication data, (>300,000 participants); datasets on physical measures (>100,000 participants) and mental health (>54,000 participants); and biological samples, including the conditions under which they were collected, (>2,950,000 samples donated by more than 150,000 participants). All data and samples are available to researchers through an access request .
