Cochrane Reviews are systematic reviews of primary research in health care and policy. They aim to provide reliable and up-to-date information to help people make informed decisions about health interventions. Each review evaluates the effectiveness of treatments, diagnostic tests, or health care strategies by analyzing data from multiple studies. These reviews are conducted by Cochrane, an international organization of researchers and health professionals. They follow strict guidelines to ensure the quality and transparency of their findings. By summarizing evidence from various studies, Cochrane Reviews help clinicians, policymakers, and patients understand what works best in health care.
