The Landmark Studies in Medicine app provides summaries of key clinical studies relevant to physicians, nurse practitioners, physician assistants, and other health professionals. The content is derived from the 50 Studies Every Doctor Should Know book series, published by Oxford University Press. It covers the disciplines of General Medicine, Internal medicine, Neurology, Pediatrics, Radiology, and Surgery, with additional disciplines coming soon. The included studies were selected using a rigorous peer review process, and whenever possible the summaries have been reviewed by the original study authors for accuracy. The content in this app truly represents information every clinician should know!
