RCT is an acronym that stands for Randomized Controlled Trial. This type of study is considered the gold standard in health research and is frequently used to evaluate the effectiveness of a new treatment or intervention. There are many synonyms for RCT, including randomized clinical trial, randomized intervention study, and randomized comparative trial. Other terms that are commonly used to describe similar types of studies include double-blind trial, placebo-controlled trial, and cross-over trial. Regardless of the exact terminology used, all of these studies involve random allocation of participants to different treatment groups in order to minimize the potential for bias and produce high-quality results.
