Patterns of Nerve Enlargement in CMT-1 and Acquired Demyelinating Polyneuropathies

	Diagnosis (n= (%))
Pattern of Nerve Enlargement	CMT-1 n=35	CIDP n=55	GBS n=21	MMN n=17
None	0 (0%)	11 (20%)	10 (48%)	6 (35%)
Mild-Type 1	2 (6%)	13 (24%)	8 (38%)	7 (41%)
Regional- Type 2	2 (6%)	11 (20%)	2 (10%)	4 (24%)
Diffuse-Type 3	31 (89%)	20 (37%)^*	1 (5%)^*	0 (0%)^*

p<0.001 compared to CMT-1

Nerves are more likely to be very enlarged on average and at multiple sites in CMT-1 than CIDP, GBS, and MMN. Average NSI in each demyelinating neuropathy group was larger (p≤0.05) than in controls.
