Note that only the first 69 pages are the article. The rest are references, as one might expect from a meta-analysis. I've skimmed it and it is really well done

Note that only the first 69 pages are the article. The rest are references, as one might expect from a meta-analysis. I've skimmed it and it is really well done. I don't think I've ever seen a better meta-analysis. I'd highly recommend reading it if only just because they explain things to look out for in other meta-analyses.
