Real-World Evidence (RWE) refers to the data collected from real-world settings, such as hospitals, clinics, and patient registries, rather than controlled clinical trials. This type of evidence helps researchers understand how treatments work in everyday situations, providing insights into patient outcomes, safety, and effectiveness. RWE is increasingly used in the fields of pharmaceuticals and healthcare to support regulatory decisions and inform clinical guidelines. By analyzing data from diverse populations, RWE can reveal how different groups respond to treatments, ultimately leading to more personalized and effective healthcare solutions.
