Data behind the portal
PRSweb publishes score files and result tables, not participant-level data from the Michigan Genomics Initiative or UK Biobank.
When reporting results, cite the paper associated with the specific release you used.
No collection-wide reuse license is stated for the portal artifacts. Terms attached to the source score models may also apply; contact the maintainer before redistributing portal files.
