They can be used to group participants into different risk categories for diseases, and are also used as covariates in epidemiological analyses. The aim of this tutorial is to provide a simple introduction to PRS analyses to those new to PRS, while equipping existing users with a better understanding of the processes and implementation "underneath the hood" of popular PRS software.
