Which of the following is NOT a requirement for clinical trials?

The requirement for clinical trials primarily revolves around ensuring transparency, ethical conduct, and public accountability. Registration of clinical trials is crucial as it allows for tracking of studies and facilitates accountability, while posting trial results is fundamental to disseminating findings and promoting informed medical decisions. Additionally, the posting of summaries on company websites helps to provide public access to information about ongoing or completed trials.

Obtaining multiple peer reviews, however, is not universally mandated as a requirement for clinical trials. While peer review is an essential component of the scientific publication process, especially for publishing results in journals, it does not fall under the regulatory requirements for conducting clinical trials. Thus, clinical trials must adhere to registration, result posting, and other facets of transparency but do not expressly require multiple peer reviews as part of the trial process itself.
