Randomized controlled trials (RCTs) are a research method used to evaluate the effects of an intervention, such as a drug, treatment, or procedure, by randomly assigning participants to receive either the intervention or a comparison condition such as a placebo or standard care. Random assignment helps ensure that the groups are similar at the outset, reducing bias and allowing differences in outcomes to be attributed more confidently to the intervention itself. Often combined with blinding and placebo controls, RCTs are considered a rigorous standard for assessing whether a treatment is effective and safe. Research in this subject area uses randomized controlled trial designs, along with systematic reviews and meta-analyses, to test interventions across many areas of medicine. Studies have applied these methods to evaluate drug combinations for hypertension, placebo-controlled trials of supplements and procedures, behavioral interventions, and treatments examined through double-blind randomized designs. This page gathers peer-reviewed, open-access research relevant to randomized controlled trials and their role in generating reliable evidence on the effectiveness and safety of interventions.
