Figure 2. Comparisons of White Matter Hyperintensity Lesion Loads in Different Time Intervals From Disease Onset.

The horizontal lines within the box indicate the median, and the + indicates the mean. The error bars indicate the 1.5 interquartile range of the lower and upper quartiles. The open circle indicates outliers. The following outliers with a volume greater than 6 cm³ are not shown in the figure: day 1-7: whole brain, 8.06 cm³ and 10.35 cm³; day 15-21: whole brain, 16.33 cm³; periventricular, 11.39 cm³; and day 29-60: whole brain, 6.24 cm³.
