There are four levels of evidence quality when rating an Evidence-Based Practice.

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (A)

The main idea here is how evidence quality is organized to reflect confidence in a practice’s effectiveness. In the framework used for Evidence-Based Practice, there are four levels of evidence quality. The strongest level comes from well-designed randomized controlled trials and systematic reviews or meta-analyses of those trials. The next level includes controlled studies without randomization. The third level consists of observational studies, which can show associations but are more prone to bias. The lowest level covers case series and expert opinion, which provide less rigorous support. This four-level structure helps clinicians weigh how much trust to place in the findings when deciding whether to adopt a practice. So the statement is true.
