Interventional research involves using various interventions or treatments to study the efficacy and safety of different therapies, procedures, or technologies. This type of research typically involves randomized controlled trials, systematic reviews, and meta-analyses to evaluate the effectiveness of interventions in improving health outcomes. Interventional research is commonly used in clinical trials to test new drugs, medical devices, surgical techniques, or behavioral interventions. It aims to provide evidence-based recommendations for clinicians and policymakers to improve patient care and advance medical science.
