Meta-analysis can identify large-scale trends across multiple groups of data.

• A. Meta-analysis can identify large-scale trends across multiple groups of data
• B. It measures patient satisfaction at a single site
• C. It is used to compute cost-effectiveness at one hospital
• D. It describes data entry procedures

Answer: (A)

Meta-analysis synthesizes results from several studies to find overall patterns across diverse groups. By pooling data, it increases statistical power, yields a more precise estimate of the effect, and shows whether results are consistent or variable across different settings. This makes it well-suited to identifying large-scale trends across multiple groups of data. In contrast, evaluating patient satisfaction at a single site, computing cost-effectiveness at one hospital, or describing data entry procedures each focus on a single context or a specific process rather than combining evidence from multiple studies.
