A systematic review is an overview that answers a specific clinical question and contains a thorough, unbiased search of the relevant literature, explicit criteria for assessing studies, and a structured presentation of the results.

Introduction to systematic review and meta-analysis

Systematic reviews and meta-analyses present results by combining and analyzing data from different studies conducted on similar research topics. In recent years, systematic reviews and meta-analyses have been actively performed in various fields including anesthesiology. These research methods are powerful tools that can overcome the difficulties in performing large-scale randomized controlled trials. However, the inclusion of studies with any biases or improperly assessed quality of evidence in systematic reviews and meta-analyses could yield misleading results. Therefore, various guidelines have been suggested for conducting systematic reviews and meta-analyses to help standardize them and improve their quality. Nonetheless, accepting the conclusions of many studies without understanding the meta-analysis can be dangerous. Therefore, this article provides an easy introduction to clinicians on performing and understanding meta-analyses.

In the previous chapter Chapter 22 , The Process of a Systematic Review and Meta-analysis , we provided guidance on how to evaluate the credibility of the process of a systematic review with or without a meta-analysis. In this chapter, we address how—if the systematic review is sufficiently credible—to decide on the degree of confidence in the estimates that the evidence warrants. As you will see, systematic review authors may have conducted a credible review and analysis and one may still have little confidence in the estimates of effect. We will return to the clinical scenario discussed in the previous chapter and obtain the relative and absolute effects of the intervention from a credible systematic review and meta-analysis 1 and determine the confidence in these estimates quality of evidence.

To inform evidence-based practice in health care, guidelines and policies require accurate identification, collation, and integration of all available evidence in a comprehensive, meaningful, and time-efficient manner. Approaches to evidence synthesis such as carefully conducted systematic reviews and meta-analyses are essential tools to summarize specific topics. Unfortunately, not all systematic reviews are truly systematic, and their quality can vary substantially. Since well-conducted evidence synthesis typically involves a complex set of steps, we believe formulating a cohesive, step-by-step guide on how to conduct a systemic review and meta-analysis is essential. While most of the guidelines on systematic reviews focus on how to report or appraise systematic reviews, they lack guidance on how to synthesize evidence efficiently. To facilitate the design and development of evidence syntheses, we provide a clear and concise, step guide on how to perform a systematic review and meta-analysis of observational studies and clinical trials.
