Clinical Evidence Uncovered: What Really Works in Medicine is a guide to understanding how decisions in medicine are supported by data. Clinical evidence describes information gathered from studies that test ideas about interventions and their impact. By centering on robust clinical evidence, this page helps readers distinguish between results that come from well-designed trials and those that come from less reliable sources. Learn how rigorous trials and transparent reporting shape what we know. Key sources of clinical evidence include randomized controlled trials, systematic reviews, meta-analyses, and well-conducted observational studies. Each design offers different strengths and limitations. Randomized trials reduce bias by randomly assigning participants, while systematic reviews synthesize findings across multiple trials. Together, they form a hierarchy that informs how confidently we can apply results to practice. Recognize that clinical evidence evolves as new data emerge. Interpreting clinical evidence requires scrutiny of how studies are conducted and reported. Look for clarity about endpoints, sample size, and the magnitude of observed effects, not just statistical significance. Consider replication across studies, potential biases, and how results translate to real-world settings. Publication bias and selective reporting can skew the evidence base, underscoring the need for preregistration and open methods. Our coverage aims to present clinical evidence in clear, balanced terms and to link findings to their practical implications. We curate sources that meet high methodological standards and offer context so readers can form informed judgments.
