FIGURE 3.

Means (95% CIs) estimated by using an intention-to-treat analysis with multiple imputation. A repeated-measures mixed model was used to examine time, group, and treatment × time interaction at each time point. A significant effect of time was observed for the DB (n = 105), WA (n = 108), and AC (n = 105) groups at 0–3 mo (P < 0.001) and 0–6 mo (P < 0.001). There were no significant treatment × time interactions between the WA and AC groups or between the DB and AC groups at any time. AC, attention control; DB, diet beverage; WA, water.
