AMYPAD PNHS - Data Access Request

Biospecimen access Are biospecimens available in the data source (e.g., tissue samples)?: No

Access to subject details Can individual patients/practitioners/practices included in the data source be contacted?: No

Event triggering registration

Event triggering registration of a person in the data source: Other

Event triggering registration of a person in the data source, other: Admitted to research cohort

Event triggering de-registration of a person in the data source: Other

Event triggering de-registration of a person in the data source, other: Withdraw of consent to be included in Parent Cohort

Event triggering creation of a record in the data source: Inclusion in Parent Cohort

Data source linkage

Linkage Is the data source described created by the linkage of other data sources (prelinked data source) and/or can the data source be linked to other data source on an ad-hoc basis?: Yes

Linkage description, pre-linked: The current version of the dataset integrates information from 10 Parent Cohorts: ALFA+, AMYPAD DPMS, DELCODE, EMIF-AD (60++ and 90+), EPAD LCS, FACEHBI, F-PACK, Microbiota, and UCL-2010-412
Each participant enrolled in the AMYPAD PNHS study received a unique identifier that was matched by the parent cohort to their original unique identifier.
Linkage Strategy - Deterministic
Linkage is based on unique subject identifier (person_id) and visit identifier (visit_id)
