Literature

Review A literature review is a critical summary and evaluation of the current published research literature on a specific research topic. It is used to assess the current state of knowledge on the topic, identify areas of agreement and disagreement among authors, identify gaps in knowledge and understanding, and provide a foundation for new research. By conducting a systematic review of the literature, researchers can ensure that their studies are not unnecessarily replicating past work and have the potential to develop new knowledge. Literature reviews can be used to inform the design of clinical trials, to support evidence-based practice, to inform health policies and to develop and refine clinical guidelines.
