Values represent median (upper number in each cell) and interquartile range (lower number in each cell) for percent of area injured by stroke (%) and lesion centrality ratio (cr, where >1 equals central, and <1 peripheral position relative to the affected area. Abbreviations: A, B, C = recovery subgroups, CST = corticospinal tract; hIP = human intraparietal sulcus; SLF = superior longitudinal fasciculus. § = total lesion volume (in cc).
