Which feature is commonly found in systematic reviews?

• A. A focus on anecdotal evidence.
• B. A synthesis of observations from clinical experience.
• C. A focus on randomized clinical trials.
• D. A comparison of various observational studies.

Answer: (C)

A systematic review is a rigorous and structured approach to summarizing the available evidence on a specific research question, typically employing a comprehensive and repeatable methodology. A primary feature of systematic reviews is their emphasis on high-quality research, particularly randomized clinical trials (RCTs). This is because RCTs are considered the gold standard in clinical research due to their design, which minimizes bias and allows for more reliable conclusions about the effectiveness of interventions. Systematic reviews seek to aggregate findings from multiple RCTs to provide a consolidated assessment of the evidence, which helps inform clinical guidelines and decision-making. By focusing on RCTs, systematic reviews can achieve a higher level of certainty about the effectiveness of a treatment or intervention compared to anecdotal evidence, observational studies, or clinical experience alone. The other options involve less rigorous types of evidence or methods that are not the primary focus of systematic reviews. Anecdotal evidence lacks the scientific rigor needed for strong conclusions, while observations based on clinical experience may introduce bias and variability. Although observational studies are valuable, they do not provide the same level of evidence as RCTs, and comparing them is typically not the main purpose of a systematic review. Hence, the distinct focus on randomized clinical trials is what makes this choice
