Description Meta-analysis is a statistical analysis of data combined from two or more studies. Different studies use different variables measured
on different scales. Meta-analysis is a method of standardizing the studies so that results can be more easily compared. Meta-analysis
is a useful tool for evidence-based medicine. Articles in this issue examine the strengths and limitations of meta-analysis in infectious
diseases, the use of meta-analysis in comparing diagnostic tests or treatments, and meta-analysis for specific problems, such as parasitic
infections, HIV, surgical infections, and pediatric infections.
