What is comparative effectiveness research?

Comparative effectiveness research (CER) is a field of study that compares different healthcare interventions and strategies to determine which work best for specific populations or conditions. The goal is to provide evidence on the effectiveness, benefits, and harms of various treatment options so patients and healthcare providers can make informed decisions. CER often uses real-world data and clinical trials to evaluate how treatments perform in routine practice, not just controlled settings. This research helps improve healthcare outcomes and ensures resources are used efficiently.
