Which evidence level includes case reports and narrative literature reviews?

• A. Level 2
• B. Level 3
• C. Level 4
• D. Level 5

Answer: (D)

The correct answer reflects the hierarchy of evidence in research, particularly in the context of clinical practice guidelines and evidence-based practice. Level 5 evidence typically encompasses expert opinions, narrative reviews, and case reports. These types of evidence provide insights and observations based on clinical experience and individual cases, but they lack the systematic methodologies and controls seen in higher levels of evidence. Case reports and narrative literature reviews are valuable for generating hypotheses and showcasing unique cases, but they do not offer the rigorous data collection and analysis found in randomized controlled trials or cohort studies, which would be classified at higher levels of evidence. In evidence-based practice, understanding the distinctions between levels of evidence is crucial for making informed clinical decisions, especially when determining the effectiveness of interventions for pediatric clients in occupational therapy.
