Randomized controlled trials
Randomized controlled trials (RCTs) are research studies used to test the effectiveness of new treatments or interventions. Participants are randomly assigned to different groups: one group receives the treatment, while the other gets a placebo or standard care. This random assignment helps eliminate bias, ensuring that the results are reliable. By comparing outcomes between the groups, researchers can determine whether the treatment works and how well it performs. RCTs are considered the gold standard in clinical research because they provide strong evidence about cause-and-effect relationships.

A Randomized Controlled Trial (RCT) is a scientific study designed to assess the effectiveness of a treatment or intervention. Participants are randomly assigned to two or more groups: one group receives the treatment, while the other (the control group) does not. This random assignment helps eliminate biases and ensures that the groups are comparable. Researchers then compare the outcomes between the groups to determine if the treatment has a significant effect. RCTs are considered the gold standard in research because they provide strong evidence for establishing causality and making informed decisions about medical or behavioral interventions.

A randomized controlled trial (RCT) is a research method used to test the effectiveness of a treatment or intervention. In an RCT, participants are randomly assigned to either the treatment group or a control group, which receives a placebo or no treatment. This random assignment helps eliminate bias and ensures that the results are due to the treatment itself. Researchers then compare the outcomes between the two groups to determine if the treatment had a significant and measurable effect. RCTs are considered the gold standard in clinical research because they provide strong evidence for causal relationships.
