OpenSAFELY Association between warfarin and COVID-19-related outcomes compared with direct oral anticoagulants: population-based cohort study

This is the code and configuration of our pre-print paper available on MedRxiv here. You can sign up for the OpenSAFELY email newsletter here for updates about this study and other OpenSAFELY projects.

• The paper is now under here.
• Raw model outputs, including charts, crosstabs, etc, are in released_outputs/
• If you are interested in how we defined our variables, take a look at the study definition for people with atrial fibrillation, how we derive variables; this is written in python, but non-programmers should be able to understand what is going on there
• If you are interested in how we defined our code lists, look in the codelists folder. All codelists are available online at OpenCodelists for inspection and re-use by anyone
• Developers and epidemiologists interested in the framework should review the OpenSAFELY documentation

About the OpenSAFELY framework

The OpenSAFELY framework is a new secure analytics platform for electronic health records research in the NHS.

Instead of requesting access for slices of patient data and transporting them elsewhere for analysis, the framework supports developing analytics against dummy data, and then running against the real data within the same infrastructure that the data is stored. Read more at OpenSAFELY.org.
