The second edition of the book “An Evidence-Based Clinical Textbook in Obstetrics and Gynaecology for MRCOG-2” has been primarily inspired by the success of the first edition. Similar to the previous edition, the second edition has also adopted an evidence-based approach, especially focussing on the current standards in health care. It helps in the amalgamation of clinical expertise, patient values, and the best research evidence so that it can be used in the decision-making process for patient care. The previous categorisation of the book into three parts: general, obstetrics, and gynaecology as well the pattern of previous sections have been retained in this comprehensive new edition.
