The basic, translational and clinical content in Nature Reviews Gastroenterology & Hepatology is written by internationally renowned basic and clinical academics and researchers and targeted towards readers in the biological and medical sciences, from postgraduate level upwards. While intended to be read by practising doctors, researchers and academics within a specialty, we aim to make all our articles accessible to readers working in any biological or medical discipline.In-depth Reviews present authoritative, up-to-date information on a topic, placing it in the context of a field's history and development.
