FIG 2. Scatter plot of the coefficient <D> data points for the relapsing-remitting (RR, 10 points), secondary-progressive (SP, 10 points), and control group (NWM, normal white matter, 11 points). Each point corresponds to one subject and represents the mean value of <D> as obtained in each subject from all the ROIs that were drawn on the T2-weighted (b = 0) images. Graph shows there is no overlap between the relapsing-remitting and secondary-progressive groups
