What is one reason for retaining informed consent documents in research?

Retaining informed consent documents is crucial in research because it serves as evidence that participants have agreed to take part in a study under specific conditions, fully understanding the nature of the research, its risks, and their rights. This documentation not only supports the integrity of the research process but also acts as a form of protection against potential ethical violations. In the event of any disputes or questions about the research conduct, having these documents readily available ensures that researchers can demonstrate compliance with ethical standards and that participants were adequately informed about the study. This practice is essential for maintaining trust in the research process and safeguarding the welfare of participants.
