Erratum to: Depicted serving size: cereal packaging pictures exaggerate serving sizes and promote overserving

Erratum The authors re-ran the analyses for both studies, hoping to correct any minor discrepancies prior to publication of this article [1]. They regret having missed the last chance to make minor adjustments to the article prior to publication. Due to this, they include corrections to the stats as described below. In summary, corrections to Study 1 include minor tweaks to statistics of no more than 1 calorie, adjusting percent difference in calories by about 1%. Corrections to Study 2 include analysis dropping both observations from one participant who overserved by more than 3 SDs, as described below, and minor adjustments to the statistics. No findings or conclusions are impacted by these corrections. In fact, by and large the adjustments offer slightly stronger results. Corrected tables include the updated numbers, easily comparable to the manuscript initially published online. Abstract Corrections to numbers reported in results, as follows: Results: Study 1 demonstrated that portion size depictions on the front of 158 cereal boxes were 65.84% larger (221 vs. 133 calories) than the recommended portions on nutrition facts panels of those cereals. Study 2 showed that boxes that depicted exaggerated serving sizes led people to pour 20% more cereal compared to pouring from modified boxes that depicted a single-size portion of cereal matching suggested serving size. This was 45% over the suggested serving size. Methods Study 2. Observations from one participant, who served 253 grams of cereal, three SDs above the mean (SD = 50.79), were eliminated from analysis.
