I'm afraid I don't have those data; I recorded the countries while doing the summaries. I tried to mark RCTs, so you could sum up an RCT / non-RCT, but it's possibly that I didn't catch every one. (And then there's the question of how to categorize lab experiments and lab-in-the-field experiments.) 

I will say that I was quite struck while summarizing the work at how many non-RCT papers there were: Lots of interesting historical analysis, event studies, panel data analysis, descriptive work, and more.
