Health-Analytics Data to Evidence Suite (HADES) is the set of open source R packages developed and maintained by the HADES workgroup and used in almost all OHDSI studies. We finally have a paper published that describes HADES at a high level: IOS Press Ebooks - Health-Analytics Data to Evidence Suite (HADES): Open-Source Software for Observational Research.
Please recognize the hard work of the HADES developers when using any of its packages (e.g. through Strategus) by citing this paper!
