Table 3.
Mean (±SD) values of bilaterally averaged [11C]FEOBV VAChT distribution volume ratios in the patients with PD without versus with falls. Levels of statistical differences between groups are also presented (values with an asterisk remain significant after correction for Holm-Bonferroni multiple testing).
