We believe that all researchers should share their analytic code. Open sharing provides an unambiguous record of the analytical methods used, aiding reproducibility and error spotting. It also permits efficient re-use by other researchers. This is why we share all source code for all our projects, including OpenPrescribing, OpenPathology, OpenSAFELY and FDAAA Trials tracker is available on our main GitHub account. In addition, every paper we publish has its code shared, linked to from the page where you can see exactly how the code runs against the underlying data. This is all part of our open working ethos, and our other core value: combining best practice from the academic and software development communities.
