Columns in the table show estimates from different regressions. Estimates that were used to compare outcome variables across conditions are typed in bold. Coefficient estimates for reference categories are zero. Four versions of Model 2 were estimated, using in each version a different condition as the reference category. Condition 1: Brand logos + text, Condition 2: Brand logos + old text + old pictures, Condition 3: Brand logos + new text + new pictures, Condition 4: PP + old text + old pictures, Condition 5: PP + new text + new pictures. *** p < 0.01, ** p < 0.05, * p < 0.10
