A Cochrane Review is a systematic analysis of research studies that evaluates the effectiveness of healthcare interventions. Conducted by the Cochrane Collaboration, these reviews aim to provide reliable and up-to-date information to help healthcare professionals make informed decisions. They gather and assess evidence from various studies, ensuring that the findings are comprehensive and trustworthy. The reviews cover a wide range of topics, including treatments, diagnostic tests, and health policies. By synthesizing data from multiple sources, a Cochrane Review helps identify what works best in healthcare, ultimately improving patient outcomes and guiding future research efforts.
