OpenSAFELY ehrQL table of contents🔗
Danger
This page discusses the new OpenSAFELY Data Builder for accessing OpenSAFELY data sources.
Use OpenSAFELY cohort-extractor, unless you are specifically involved in the development or testing of Data Builder.
OpenSAFELY ehrQL and its documentation are still undergoing extensive development. We will announce when ehrQL is ready for general use on the Platform News page.
Note
This is a temporary page to provide links to any ehrQL documentation, while that documentation is not yet ready for a general audience.
If you start a new ehrQL page, add it here too.
The ehrQL pages will eventually be displayed in the table of contents as generated by MkDocs, and this page will be removed.
