Boxplot of semi-automatic quantification of the of the DAB stained area as percentage of the ROI. in the demyelinated center of lesions compared to normal appearing matter. Boxplots represent the mean, the 1st and 4th quartile and the minimum and maximum value. Post-hoc testing was done between WM groups and between GM groups. N = 15 for NAWM, N = 10 for active WML, N = 7 for chronic-active WML, N = 5 for leuko WML, N = 16 for NAGM, N = 8 for subpial GML, N = 5 for leuko GML. # = p = 0.07, ^* = p < 0.05, ** = p < 0.01, *** = p < 0.001
