Studies for sample size or quality?

Yes, the *metan* command will perform meta-analysis using simply the four
cells of the 2x2 table such as you describe. Type *help metan* to see the
many many options available to you. If you want to perform meta-analysis of
failure (instead of cure) simply subtract:
#treated - # cured = # failed
