Which statement accurately reflects how evidence is weighted in evidence-based practice?

• A. All evidence is created equal.
• B. Best available evidence should be used.
• C. Only randomized trials matter.
• D. Anecdotal experience is the only source.

Answer: (B)

In evidence-based practice, you weigh evidence by quality, relevance, and applicability rather than treating everything as equal. You prioritize the best available evidence—the strongest and most relevant research available—to answer a clinical question, while also considering your clinical expertise and the patient’s preferences and context. This approach often places systematic reviews and well-conducted randomized trials near the top of the hierarchy, but it also values good observational studies when RCTs aren’t available or feasible and recognizes their limitations. Anecdotes or personal experience, while informative, are the least reliable on their own and should not be the sole basis for decisions.

So the statement that best describes this weighting is that you use the best available evidence.
