Table 2 Unadjusted means of primary and secondary outcome variables for the study arms (N = 146)

  1. aEven though there is only one Control condition, we needed to identify two proportions, one for the products that would have been labeled in the Within-category arm and one for the products that would have been labelled in the Across-category arm; CI stands for Confidence Interval
