Statistical analysis

Statistical models are used in meta-analyses of data in systematic reviews of diagnostic test accuracy.

Models can be run in a variety of different software programmes but this facility is not available in RevMan. Specific statistical parameters from the models run can be input into RevMan in order to draw appropriate graphical displays of the data.

Researchers have prepared macros for statistical models for meta-analysis of data from diagnostic test accuracy studies for several statistical analysis software programs.  As these become available we will add them to this page.

Macro 1

METADAS: A SAS macro for meta-analysis of diagnostic accuracy studies. User guide version 1.0 beta.  December 2008.  METADAS (PDF 898KB)

Macro 2

METANDI: Stata module to perform meta-analysis of diagnostic accuracy. Harbord 2008

A user-written model for Stata for metaanalysis of DTA studies without covariates with results in both bivariate and HSROC parameterisations, and on a graph.

This module may be found from within Stata by typing 'findit metandi' or installed from within Stata by typing 'ssc install metandi'
