Which of the following is a type of preappraised evidence?

Clinical practice guidelines represent a type of preappraised evidence because they synthesize a body of research on a particular topic to provide recommendations for best practices in clinical settings. These guidelines are developed by experts in the field and are based on a thorough review and evaluation of available evidence from studies, making them a reliable resource for health professionals. They help clinicians make informed decisions by offering evidence-based recommendations tailored to various patient scenarios.

In contrast, textbooks, while they may contain valuable information, are generally not considered preappraised since they may present information without the rigorous evaluation of current evidence. Case studies provide insights into specific instances but do not systematically synthesize evidence across multiple cases. Opinion articles often reflect individual perspectives rather than a consensus based on robust evidence, making them less reliable as a source of preappraised information.
