No role for quality scores in systematic reviews of diagnostic accuracy studies (2005)
Whiting, Penny, Harbord, Roger, Kleijnen, Jos
Abstract Background There is a lack of consensus regarding the use of quality scores in diagnostic systematic reviews. The objective of this study was to use different methods of weighting items...

METAN: Stata module for fixed and random effects meta-analysis
Ross Harris, Mike Bradburn, Jon Deeks, Roger Harbord, Doug Altman, Thomas Steichen, ...
These routines provide facilities to conduct meta-analyses of data from more than one study and to graph the results. Either binary (event) or continuous data from two groups may be combined using...

In a cross-sectional study Davey Smith and colleagues show why observational studies can produce misleading claims regarding potential causal factors for disease, and illustrate the use of mendelian...
METANDI: Stata module to perform meta-analysis of diagnostic accuracy
metandi performs meta-analysis of diagnostic test accuracy studies in which both the index test under study and the reference test (gold standard) are dichotomous. It fits a two-level mixed logistic...
METAREG: Stata module to perform meta-analysis regression
metareg performs random-effects meta-regression on study-level summary data. This is a revised version of the program originally written by Stephen Sharp (STB-42, sbe23). The major revisions involve...
