How to Interpret and Evaluate a Meta-Analysis in the Field of Speech-Language Pathology: A Tutorial for Clinicians

Abstract

Purpose: This tutorial will provide speech-language pathologists with practical considerations and pragmatic tools for interpreting and critically evaluating a meta-analysis. Meta-analysis, which is a statistical procedure that involves combining research data across multiple high-quality research studies, is often considered the highest level of research evidence. Although meta-analyses are commonly deployed in clinical research after completing a systematic review, few clinicians or clinician scientists within the field of speech-language pathology receive formal training to conduct, interpret, or assess meta-analyses to determine the effectiveness of a treatment or procedure for evidence-based practice.

Conclusion: Clinicians within the field of speech-language pathology may use the foundational knowledge and practical guidelines outlined in this tutorial about meta-analyses to expand their knowledge of research methods and to shape their clinical practice.
