Implement Meta-analysis of Diagnostic Accuracy Tests Using mada Package of R

The mada package is a type of package that is especially used for implementing meta-analysis of diagnostic accuracy tests. This package is developed on basis of classical statistical theories and it can be used to calculate all relevant effect size of diagnostic accuracy tests; however,it does not provide pooled values of sensitivity and specificity. This article uses an example to introduce the whole functions of mada package in implementing meta-analysis of diagnostic accuracy tests,including data preparation,calculation implementation,result summary,and plots drawing.
