Model 5 Estimated effect of caloric beverages replacing caloric beverages, holding food energy constant

Lower Bound Upper Bound
Change in food energy (100 kcal) 100 <0.0001 99.9 101

*Model 3 is a composite of 8 regressions, one for each beverage, adjusted for change in total weight of beverages; coefficients express the change in energy intake associated with a change in one beverage type and a corresponding reduction in others, i.e. constant total beverage intake.
