Question

Can you please rewrite this in your own words: Quantitative synthesis (meta-analysis) and group judgment methods give us ways to summarize current states of knowledge and sometimes to predict the future. Similarly, cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA) offer ways of introducing costs and economics into these assessments.

Answer 1

Thanks to the advances in quantitative synthesis -which has to do with analysis of meta data-, and group judgement methods, there are new methods available to us to make a conclusive summary of available knowledge and sometimes using such data to accurately predict the future.

Other methods such as cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA) help to introduce the economics side of such research.
