Dear all,

A new meta-analysis package, -ipdmetan-, is available from SSC with thanks
to Kit Baum.

The main program carries out two-stage inverse-variance IPD meta-analysis
by looping over a series of categories, fitting the desired model to the
data within each.  The screen output and forestplot are based on those in
the existing program -metan-, with thanks to Ross Harris and others.

A variety of analyses are possible: a greater variety of random-effects
models are available; aggregate data may be included from an external
dataset; and a separate program -ipdover- may be used to create a
forestplot of a series of (potentially overlapping) subgroups within a
single study or trial.  The forestplot routine from -metan- has been
updated and can now be run by itself (program -forestplot-).  It now has
greater flexibility in terms of rendering; and titles, formatting etc may
be tweaked by making changes to the dataset itself beforehand.

Help files are available, but no examples as yet, sorry!  Please contact me
if you have any questions, problems or suggestions.

Many thanks,


David Fisher
