Can someone guide me towards studies, meta-reviews or collections of studies which quantifies the effectiveness of various interventions? I.e. "$10 000 spent on deworming medication in Sub Saharan countries saves on average 1 life" or "access to clean water wells in Sub Saharan countries increased educational performance by x points". Thanks!
