A histogram represents the distribution of differences in means between post-20212023 and 20002013. The horizontal axis is labeled Difference in Means (Post - Pre) and ranges from 0.4 to 1.2. The vertical axis is labeled Density and ranges from 0.0 to 3.5. The histogram has approximately 20 vertical bars, each representing a bin of data. The mean difference is marked with a red dashed line at 0.82. The 2.5 percent quantile is marked with a blue dashed line at 0.57, and the 97.5 percent quantile is marked with a blue dashed line at 1.08. The distribution appears to be roughly symmetric with a peak around the mean difference. The color of the bars is green.Posterior mean distribution (1,000 samples): post-2021–2023 against 2000–2013
