All coefficient were calculated with adjustment for clustering by kindergartens.

^# This multivariable model included two-way interaction of follow-up time and the factors significantly associated with the hand hygiene compliance before the intervention, and adjustment for clustering by kindergartens. P-value obtained in this model examines the interaction for evidence of intervention effect modification.
