As a young physician in the United States, I am constantly impressed by the excellent registry based studies coming out of Europe, in particular from the Scandinavian countries. This study is a great example. Another innovative example that comes to mind is the TASTE trial (nejm.org/doi/10.1056/NEJMoa130...). I hope the authors could comment on what are the unique aspects of the Swedish healthcare system that make such studies feasible? What are some foreseeable barriers that prevent other countries from emulating?
