The benefit of zinc for the treatment of diarrhoea in a
cluster-randomized trial of children, aged 3-59 months, living in rural
Bangladesh was previously reported. Here, the benefits of zinc
stratified by age-3-5 months, 6-11 months, and 12-59 months-are
reported. Although the sample sizes in the stratified groups were too
small to detect statistical significance in the 3-5-month and
6-11-month age-groups, the trends suggest that there may be a benefit
of zinc for the treatment of diarrhoea on the duration of diarrhoea and
on subsequent morbidity and mortality. Additional research is needed to
better understand the effect of zinc for the treatment of diarrhoea
among infants aged less than six months
