Table 1.
Demographic and clinical features of ET patients and HCs.
Figure 1.
Results from one-sample t-test on ReHo maps for ET group (upper) and HC group (lower).
Threshold was set to p<0.05 with AlphaSim correction (cluster size >2295 mm3). The underlying structure image is Ch2 image.
Figure 2.
Difference in ReHo value between ET and HC groups.
The result was derived from two-tailed two-sample t test within combined one-sample t-test mask (p<0.05, AlphaSim corrected with cluster size >351 mm3). Warm color indicates the regions with larger ReHo value in ET than HC, while cold color indicates those with decreased ReHo in ET. The underlying structure image is Ch2 image.

Figure 3.
ROIs with abnormal ReHo in ET group compared with HCs and the correlation between mean ReHo values in each ROI and TRS-A&B scores.
The left panel shows the average ReHo value in each ROI for subjects in both ET and HC groups. The middle panel shows the location of the ROIs. The right panel shows the scattered maps of the mean ReHo against the TRS-A&B scores in regions with significant (p<0.01, uncorrected) correlations. TRS-A&B: the combination between the scores of the Fahn-Tolosa-Marin Tremor Rating Scale (TRS) part A and B.
