Statistical analysis of DRG neurons and Schwann cells ICC in CIDP patients and healthy controls.

	Controls	Patients	P value
Schwann cells IgG ICC	0/28 (0%)	3/57 (5.3%)	0.5476
Schwann cells IgM ICC	0/28 (0%)	1/56 (1.8%)	1
DRG neurons IgG ICC	3/28 (10.7%)	4/57 (7.0%)	0.6793
DRG neurons IgM ICC	2/28 (7.1%)	1/56 (1.8%)	0.2565

Moderate to strong fluorescence intensity scores, including scores two and three, and other stainings, featuring scores zero and one, from DRG neurons and Schwann cells IgG and IgM ICC experiments from patients and controls were analyzed using contingency analysis with the application of a two-tailed Fisher’s exact test, accepting an alpha-level <0.05 to determine significance.
