^*Significance probabilities (P-values) associated with the McNemar's test for a significant shift in performance of the specified behavior relative to the baseline, for the designated intervention group. Exact tests were used as needed.

^†Question not asked at the 1-month follow-up questionnaire. Information was not collected for all beverages at the 1-month follow-up.
