I was looking through the 2019 Data Network and noticed that a lot of data holders own the same database.
Does anyone know which of these databases are available in the form of flat files?
For example, I see there are 5 collaborators who hold the CPRD database in the OMOP CDM format but when I looked through the CPRD website, it looks like they are offering their data through a web-based interface only. How did these 5 data holders manage to convert the CPRD database into the OMOP CDM format without getting their hands on flat files?
Thanks in advance.
