thanks Marc,
but CMH testing supposes a common odds ratio, (hence the woolf test)

i am looking for a way to just get all the odds ratios calculated, with
a family p-values (for each one) and/or family confidence intervals
(since i am doing multiple testing then,.. data snooping..)
[i know this is easily done in SAS, but i prefer R..]

tnx,
structplot looks nice as an extra

mvg,
