Correlations Between Dendritic Swellings and (1) Other Cerebellar Features and (2) Braak AD Stage

	Dendritic swellings by LH&E	Dendritic swellings by Bielschowsky method
Analyses Including All ET Cases and Controls
Torpedo count (LH&E)	r = 0.63, p< 0.001	r = 0.59, p< 0.001
Torpedo count (Bielschowsky)	r = 0.57, p < 0.001	r = 0.55, p < 0.001
Purkinje cell count (LH&E)	r = −0.28, p = 0.11	r = −0.30, p = 0.09
Basket cell axonal plexus density	r = 0.45, p = 0.007	r = 0.58, p < 0.001
Braak AD stage
0	0.14 ± 0.38 [0, 0 – 1]	0.43 ± 0.79 [0, 0 – 2]
1	1.43 ± 1.99 [0.5, 0 – 6]	2.50 ± 3.55 [1, 0 – 10]
2	0.17 ± 0.39 [0, 0 – 1]	0.92 ± 0.90 [1, 0 – 3]
3	1.33 ± 1.63 [1, 0 – 4]	2.00 ± 2.70 [1, 0 – 1]
Analyses Restricted to ET Cases
Torpedo count (LH&E)	r = 0.58, p = 0.008	r = 0.61, p = 0.005
Torpedo count (Bielschowsky)	r = 0.48, p = 0.03	r = 0.60, p = 0.005
Purkinje cell count (LH&E)	r = −0.13, p = 0.59	r = −0.18, p = 0.47
Basket cell axonal plexus density	r = 0.32, p = 0.21	r = 0.47, p < 0.059

All r values are Spearman’s r.

For the Braak AD stage, the values are mean ± standard deviation [median, minimum -maximum].
