Preprints, sometimes referred to as working papers, are a pre-peer review version of academic papers that are uploaded to a so-called preprint server. MedRxiv, the preprint server for the medical sciences, was launched at the begin of summer 2019. I will try to post preprints of all my papers – but as clinical epidemiology is a team effort, and medicine is slow to adopt new ways of doing science, I am afraid that not all my work will end up on this list.
