There was little difference in the numbers of children in each group who developed moderate to severe AGE by day 14 (11.8% of the treatment group vs 12.6% of the placebo group). Differences in the secondary outcomes were also minimal. For example, the duration of diarrhea was 54.3 hours (medium) in the treatment group vs 52.4 hours in the placebo group. The duration of vomiting was essentially 27 hours in both groups. A total of 4.8% of the treatment group vs 4.5% of the placebo group required hospitalization for their illness, and 59.2% of both groups were febrile.
