Data are n (%) of patients, unless otherwise indicated.
Percentages reflect only patients for whom the information was available;
Statistical significance of the observed differences was determined using the χ2 test for distributions of categorical variables, the Student’s t test for means of continuous variables and the log-rank test for durations;
n=171 for rotavirus-positive patients, and n=127 for rotavirus-negative patients;
The proportions of other household members experiencing gastroenteritis were compared using a logistic regression model with generalized estimating equations to account for the correlation between members of the same household;
Within two weeks before or after the index case’s baseline physician visit. ER Emergency room
