What is a significant advantage of conducting a meta-analysis?

• A. The complexity of interpretation
• B. The larger sample size
• C. The difficulty in finding previous studies
• D. The requirement for extensive funding

Answer: (B)

The significant advantage of conducting a meta-analysis lies in the larger sample size it achieves. By synthesizing data from multiple studies, a meta-analysis can combine the results of various individual research efforts. This aggregation of data increases statistical power, allowing for more robust and reliable conclusions. A larger sample size improves the generalizability of the findings and reduces the impact of variability that might exist within smaller studies. This is particularly important in fields where individual studies may have limited populations or varied results. Additionally, the increased sample size allows for more nuanced analysis, including the ability to explore subgroups within the data. Ultimately, the combination of results enhances the strength of evidence regarding a particular hypothesis or clinical intervention, making it a valuable tool in evidence-based practice.
