Real-world data (RWD) refers to points of health information collected from patients in their usual care setting rather than randomized controlled trials (RCTs). RWD comes from sources such as electronic health records, claims databases, patient registries, wearables, mobile health applications, and social media platforms. Real-world evidence (RWE), on the other hand, is the evidence derived from RWD analysis. RWD and RWE complement clinical trial data by providing valuable information on how a treatment or medical device performs in the real world.
