The Alzheimer’s Disease Sequencing Project Phenotype Harmonization Consortium (ADSP-PHC, U24-AG074855) was established to harmonize the rich endophenotypic data across cohort studies to enable modern genomic analyses of ADRD. Our mission is to work in coordination with ADSP workgroups and initiatives to streamline access to endophenotype data, provide high quality phenotype harmonization across domains, and provide comprehensive documentation of both data availability and harmonization procedures.

The first was to use "draw" as an anchor to estimate "udsbentc" and "psy021". Then "draw" became an anchor to estimate "psy247" and "psy025". Knight ADRC had an evolving cognitive battery, meaning they did not administer the same items over time, and consequently no cognitive visit with item "udsbentc" met the criteria to have a harmonized score.

Clinical & Demographic Demographics PHC_Visit Harmonized Visit Number Integer Given differences in visit codes across cohorts, we built a harmonized Visit variable simply counting each sequential visit within each study starting with the first visit with cognitive data and ending with the last visit with cognitive data. For biomarker data, PHC_Visit corresponds to the matching cognitive PHC_Visit where biomarker draw dates were within 90 days of the given cognitive visit.

Cognition Visuospatial udsbentc KnightADRC Total score for copying the Benson figure Integer Table extent of 0. Knight ADRC VSP had to be estimated in two steps. The first was to use "draw" as an anchor to estimate "udsbentc" and "psy021". Then "udsbentc" became an anchor to estimate "psy247" and "psy025". Knight ADRC had an evolving cognitive battery, meaning they did not administer the same items over time, and consequently no cognitive visit with item "udsbentc" met the criteria to have a harmonized score.
