Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.

PSS001080 Cases included incident Alzheimer's disease (AD) and other types of incident dementia. Of the 1,609 dementia cases, 1,262 were individuals with AD and 347 were individuals with other types of dementia excluding AD. A consensus panel led by a consultant neurologist established the final diagnosis according to standard criteria for dementia (Diagnostic and Statistical Manual of Mental Disorders III-revised) and Alzheimer’s disease (National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and Related Disorders Association). Of the total 12,255 individuals, APOE genotypes were available for 11,375. From those genotyped, 261 individuals were homozygous for APOE ε4 (ε4/ε4). Of the 261 ε4/ε4 individuals, 72 had AD whilst 11 had other types of dementia excluding AD. Median = 10.9 years

PSS001081 Cases were individuals with incident-all cause dementia. Dementia was diagnosed using Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria. Diagnosis date was recorded as date of trigger. Dementia cases were sub-classified into either 'probable Alzheimer's Disease (AD)', 'possible AD' or 'non-dementia AD' using the 2011 NIA-Alzheimer's Association core clinical criteria. Of the 324 cases, 143 were classified as 'probable AD', 176 were classified as 'possible AD' and 5 were classified as 'non-AD related dementia'. Median = 4.5 years
