Distributions of normalized change in PDLvoxel for WA, DB, and VB. The distributions were calculated by smoothing histograms using Gaussian filters with standard deviation equal to 0.001 times the SD of the data. The box plots indicate quartile deviations. The distribution for the DB had more positive values, with values as high as 119%, whereas the distribution for the VB had more negative values with values as low as −15%. Both distributions had several points lesser than the first quartile and greater than the third quartile. Download Figure 3-1, EPS file.
