We are working on getting more materials up online. It’s a long process, but to start, here are some documents describing the process used in our current round of meta-analyses.
This diagram describes our process. The meta-analyses follow the standard stages: (1) topic selection; (2) a search for relevant papers; (3) screening of papers; (4) data extraction; and (5) data analysis. In addition, we pay attention to (6) dissemination and (7) updating of results, so as to allow our work to serve as a resource for others and improve the overall data quality.
