Figure. Total calories per order (n = 335) before and after enactment of the San Francisco Healthy Food Incentives ordinance, for children ordering a children’s meal at 2 national restaurant chains in San Francisco, 2011–2012. Mann–Whitney U tests were used to test for comparisons between time points. The horizontal line in the middle of each box indicates the median, and the top and bottom borders of the box mark the 75th and 25th percentiles, respectively. The upper whisker extends to the largest data point within 1.5 IQR of the upper quartile while the lower quartile extends to the smallest data point within 1.5 IQR of the lower quartile. Points beyond the whiskers are shown as dots. Abbreviations: Pre 1, pre-ordinance time point 1; Pre 2, pre-ordinance time point 2; Post, post-ordinance time point. Abbreviation: IQR, interquartile
range.
