An Overview of Meta-analysis for Dental Researchers.

In order to keep clinical norms aligned with evidence-based practices, dental researchers need to be equipped to read and evaluate meta-analyses. Moreover, clinician scientists in dentistry should be prepared to lead investigations that incorporate meta-analysis. This article provides an overview of the principles and practices that will equip dental researchers to engage in meta-analysis work. Six elements of meta-analysis are addressed: formulating a research question, searching the literature, collecting the data, aggregating the data, analyzing the data, and interpreting results and drawing generalizations. Readers are guided through each of these stages of research so that they can recognize and implement robust, reproducible meta-analysis work. [ABSTRACT FROM AUTHOR]
