PGS 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.

PPM000090 PGS000038 (PRS90) PSS000057 Rutten-Jacobs LC et al. (2018) Reported Trait: Incident stroke HR (High [top 33%] vs. Low [bottom 33%] of genetic risk): 1.35 [1.21 - 1.5] age, sex, 10 PCs of genetic ancestry, genotyping batch The best performing PRS (e.g. C+T thresholds) were selected based on this sample set, as well as being used for the evaluation.

PSS000057 Incident stroke in was defined based on the UK Biobank (UKB) algorithm, based on medical history and linkage to data on hospital admissions and mortality. The authors also subtyped ischaemic stroke, intracerebral haemorrhage, or subarachnoid haemorrhage. UKB Participants with genetic data were excluded from the analysis based on the following criteria: failing genetic quality control (missingness > 5%, sex mismatch, excessive heterozygosity), having a history of stroke or myocardial infarction (MI), self-report of stroke or MI, missing lifestyle information. 306,473 individuals
