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.

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
