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.
