Randomized controlled trials (RCTs) are considered to produce the highest level of evidence in the original studies that informs the practice of evidence-based medicine (EBM). By manipulating an independent variable to study its impact on the outcome, RCTs establish causal relationships and provide valuable insights into clinical treatment. To improve patient outcomes and optimize the use of clinical resources, the practice of EBM plays a crucial role in designing and conducting RCTs to evaluate the effectiveness of clinical interventions. This review aims to explore the essential steps involved in conducting a rigorous and reliable RCT, ensuring the generation of high-quality evidence.
随机对照试验(RCTs)在为循证医学(EBM)实践提供依据的原始研究中被认为能产生最高级别的证据。通过操纵一个自变量来研究其对结果的影响,随机对照试验建立因果关系,并为临床治疗提供有价值的见解。为了改善患者预后并优化临床资源的使用,循证医学实践在设计和开展随机对照试验以评估临床干预措施的有效性方面发挥着关键作用。本综述旨在探讨进行严格且可靠的随机对照试验所涉及的基本步骤,确保产生高质量的证据。
