Comparisons across conditions
REGRESSION, REGRESSIONS, REGRESSION
Table Regression models for the three outcome variables, comparing responses across experimental conditionsColumns 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. *** In addition, the effect of PP relative to branded packages (when old warnings were displayed) (condition 4 versus 2, in column (2)) on negative affect was 0.48 points out of 5 (Effects of package design elements on outcome variables estimated through regression analyses by comparing across experimental conditions (Based on the results in Table Combined health warning compared to text-only warnings(on packages with brand logos)New warnings compared to old warnings(on packages with brand logos)PP compared to branded packages(when old warnings are displayed)PP compared to branded packages(when new warnings are displayed)New warnings compared to old warnings(on plain packages)
