PRIMARY outcome

Timeframe: 14 days

Population: Prior estimates of the sample size showed that 62 per group would have 80% power for detecting a difference of 20% in the rates of diarrhea. This was based on the placebo group having a 10% (which is consistent with published literature) rate of diarrhea. Analysis performed used the intention to treat and no imputation was required.

The primary outcome was the incidence of participants receiving antibiotics with diarrhea during the 14-day follow-up period, as determined by parental report.
