Randomized Controlled Trial

A randomized controlled trial (RCT) is a scientific study used to test the effectiveness of a treatment or intervention. In an RCT, participants are randomly assigned to two groups: one that receives the treatment and one that does not (the control group). This random assignment helps ensure that the groups are similar, making it easier to determine if any differences in outcomes are due to the treatment itself. RCTs are considered the gold standard for evaluating healthcare interventions because they reduce bias and provide reliable evidence on whether a treatment works.

    A randomized controlled trial (RCT) is a type of research study used to test the effectiveness of a treatment or intervention. In an RCT, participants are randomly assigned to either a treatment group, which receives the intervention, or a control group, which does not. This random assignment helps ensure that the groups are similar and reduces bias. Researchers then compare the outcomes between the two groups to determine if the treatment had a significant effect. RCTs are considered the gold standard in clinical research because they provide strong evidence for making decisions about healthcare practices.
