  1. Considering 0.85 as the threshold, the robust features are highlighted in bold, the others in italic (ICC = intraclass correlation coefficient, GL = grey level, NAWM = normal appearing white matter, VOI = region of interest, P = percentile, MAD = mean absolute deviation, RMS = root mean squared, AF = arcuate fasciculus, CST = cortico-spinal tract, FAT = frontal aslant tract, IFOF = fronto-occipital fasciculus, OR = optic radiation, UF = uncinate fasciculus).
