Figure 3. Ventral anterior substantia nigra magnetic susceptibility.
Mean magnetic susceptibility values in the ventral anterior substantia nigra are shown comparing Parkinson’s disease (PD) and healthy controls (HC). False discovery rate-corrected group, time and group × time interaction p-values were 0.042, 0.02, and 0.043, respectively. Comparisons were made adjusting for age and sex. The error bars represent ± 1 standard error of the mean.
Legend: PD - Parkinson’s disease; HC – healthy controls; SN–substantia nigra; ppb – parts per billion
