Yes,,my own doctor showed me such a study ,,thats how he convinced me to use an estrogen hrt
patch,,,I use
Vivelle and am quite happy with it,,,My gyno claims the "old" studies where not a good scientific study,,,he says it was all post menopausal women and that made the study biased. A good study is double blind and a good cross section of women ,,some of differnent ages and ethnic backgrounds .
I personally would advise anyone to do a lot of homework on this ...
