Randomized trials are fundamental to evidence-based medicine and are heavily emphasized in both Brazilian and international clinical research. In Brazil, regulatory bodies like ANVISA (Agência Nacional de Vigilância Sanitária) require randomized trials for drug approval, making this term essential in pharmaceutical and medical sectors. The term is primarily used in academic, medical, and scientific contexts rather than in everyday conversation.
