The generation of evidence is an ongoing process in the field of medicine. Basic and clinical research have been the pillars of modern medicine and continue to be the strength of a modern medical practitioner. With increasing number of biomedical journals and therefore research articles being published, staying updated with the current evidence is a necessity for the clinician. One of the five goals of an Indian medical graduate as prescribed by the National Medical Commission is to function as a lifelong learner committed to continuous improvement of skill and knowledge [1]. It would be ideal that any topic of concern is thoroughly searched, read, reviewed and analyzed by going through all the literature. However, this is easier said than done. This task is nothing less than swimming in the middle of an ocean with no land in sight.The variability in the quality and content of the enormous amount of information available confuses the clinician who ends up having more unanswered questions than before. It is for such situations that a state of the art, reliable, well written review article acts like a lifeboat. A review article is a comprehensive synthesis of published and unpublished material on a topic. It is a well planned and well-organized analysis of all the literature relevant to a topic of interest providing a useful summary and answers to the reader's doubts and questions. It facilitates the medical practitioner to take evidence based clinical judgements and decisions. It is a practical solution to the problems of excessive information, divergent views and lack of consensus on a topic. Review articles aid decision making in clinical practice by summarizing enormous information available, in a coherent and easily understandable form, thereby acting as guides for practicing evidence-based medicine. They facilitate in understanding of recent advances, complex topics and sub topics, which are not a part of the conventional textbooks. They help in the identification of relations, contradictions, controversies and lacunae in the existing literature, and provide a direction for future research.
