What is one advantage of meta-analysis as a method of integration?

Meta-analysis is a statistical method that combines the results of multiple studies to derive a more precise estimate of effect sizes or outcomes. One of the primary advantages of this method is its objectivity. This objectivity stems from its systematic approach to synthesizing data, which helps minimize bias in the interpretation of findings. By relying on statistical techniques to aggregate results, meta-analysis reduces subjectivity that can come from individual studies, allowing for a clear and transparent assessment of evidence across various research projects.

This objectivity is essential in the context of evidence-based practice, as it provides practitioners with reliable and reproducible results, enhancing confidence in the recommendations drawn from the synthesis. While aspects like comprehensive data collection, increased sample size, and quicker results can be beneficial, they are not foundational benefits of the meta-analysis method compared to its objective nature in evaluating research outcomes.
