What is real-world evidence (RWE) and how does it complement randomized trials in healthcare decision-making?

Real-world evidence comes from real-world data collected outside the controlled setting of randomized trials, such as electronic health records, insurance claims, and patient registries. It complements randomized trials by showing how a therapy performs in broader, more diverse patient populations, over longer timeframes, and in everyday clinical practice. This includes observing actual effectiveness beyond trial efficacy, detecting safety signals that may only emerge in routine use, and comparing different treatments as they are used in real life. While randomized trials provide rigorous proof of benefit under ideal conditions, real-world evidence adds external validity and practical context that helps inform decisions for clinicians, patients, and policymakers.
