A key aspect of randomized controlled trials: allocation concealment.

Preoperative rehabilitation, or prehabilitation, plays a crucial role in improving outcomes for patients undergoing complex surgeries like pancreaticoduodenectomy. In the article "Prehabilitation in Patients Undergoing Pancreaticoduodenectomy: A Randomized Controlled Trial" by Ausania et al., valuable insights are provided into this emerging field. However, key methodological details, such as the randomization process and allocation concealment, were not fully described. Randomization and allocation concealment are essential in randomized controlled trials to prevent selection bias and ensure valid, unbiased results. Without proper allocation concealment, the trial's outcomes may be skewed, overestimating treatment effects. This paper underscores the importance of transparent reporting of these processes to maintain scientific rigor and enhance the reliability of study findings.
