^*Each row for the non-cavitated (second column) and for cavitated caries (fourth column) was from a separate regression model, with each beverage intake frequency treated as a categorical (3-level) variable.

^**Transitions are from sound to non-cavitated lesions.

^***Transitions are from sound/non-cavitated caries lesions to cavitated caries or filled lesions.
