Table 1 Teased nerve fiber results for POEMS and CIDP biopsies

From: Nerve pathologic features differentiate POEMS syndrome from CIDP

Teased fiber condition POEMS CIDP P value
Median Range Madian Range
Normal A, B (%) 56 9–76 74 16–93 <0.01*
Demyelination: C, D (%) 9 1–31 8 1–62 =0.7
Remyelination: F, G (%) 9 3–33 9 2–23 =0.5
Axonal: E, H (%) 22 3–73 7 1–55 <0.01*
Classifiable (no.) 81 11–105 70 22–100 =0.5
Empty (no.) 17 4–75 20 2–85 =0.6
  1. Results from classifiable fibers are expressed in percentages and unclassifiable fibers (empty strands) are expressed in numbers. P value <0.05 were considered significant and are marked with a star (*) and bolded text
