c. Baltussen and others (2005). Cost-effectiveness calculations are based on data from Frick and others (2001) for mass treatment of children only, not greater efficacy reported by Bowman and others (2000) and Solomon and others (2004) for mass treatment of entire communities. The greater efficacy reported in mass treatment of entire communities may lead to better cost-effectiveness.
