  1. *The coefficient (Coeff) is the difference in total calories chosen by those in the food advertising group from the total chosen by those in the non-food-advertising group. [95% Confidence Intervals (CI) in brackets].
  2. Note: For each outcome, the results of 7 separate Tobit regressions are reported. In each regression the intervention status is the only variable. Significant results in bold.
