Why review?

Reviewing the literature is an essential initial step in any biomedical research project. It offers researchers a thorough understanding of the current knowledge on the topic and identifies gaps or areas for further investigation. Conducting a literature review before starting a new research project helps avoid duplicating research efforts, ensures the research is relevant and contributes to advancing the field. Moreover, a comprehensive literature review informs critical aspects of the research design, including the methodology, sampling strategy, and data analysis techniques.

 By leveraging existing knowledge through a thorough literature review, researchers can develop more informed research questions, build on existing knowledge, and produce more impactful findings.
