This sounds like a meta-analysis of single proportions.
You could do this, e.g., with metaprop() from R package meta or
rma.uni() / rma.glmm() from R package metafor.
In order to conduct subgroup analyses for protocols, you can use
argument 'byvar' in metaprop() or the 'mods' argument in the rma's.
This said, you must be aware that you cannot reliably compare the two
protocols using information from these one-arm studies. All differences
that you observe could be due to systematic differences in the
