What term describes the process of combining findings from several studies to identify overall trends?

• A. Databases
• B. Clinical practice guidelines
• C. Systematic reviews
• D. Bias

Answer: (C)

Systematic reviews summarize the best available evidence by collecting all relevant studies on a topic, applying predefined criteria, assessing the quality of those studies, and combining their findings to reveal overall trends or effect sizes. This structured, transparent approach helps reveal the weight of evidence across multiple investigations, reducing the influence of any single study and making the conclusions more reliable. When data allow it, a meta-analysis may be used to calculate an overall estimate across studies. Databases are just collections of studies, not syntheses. Clinical practice guidelines translate evidence into actionable recommendations. Bias refers to systematic errors that can distort findings.
