Abstract: The WHO recommends mass drug administration (MDA) for intestinal worm infections in areas with >20% infection prevalence. Recent Cochrane meta-analyses endorse treatment of infected individuals but recommend against MDA. We conducted a theory-agnosticrandom-effects meta-analysis of the effect of multiple-dose MDA and a cost-effectiveness analysis.We estimate significant effects of MDA on child weight (0.15 kg, 95% CI: 0.07, 0.24; p
