The objective of this study was to determine whether zinc with oral rehydration solution (ORS) is more cost effective than ORS alone in the treatment of acute diarrhoea. The authors concluded that use of zinc with ORS reduced the total cost and duration of acute diarrhoea. The cost-effectiveness ratio (ICER) suggests cost effectiveness of zinc supplementation but there is a need to further assess the role of zinc supplementation in a larger population.
