Clinical and electrodiagnostic features of 46 Non-Responders (NR) and 54 Responders (R) to treatment for CIDP.

Data are means ± SD unless otherwise indicated.
Differences in categorical variables were assessed in three-group comparisons using the χ2-test, while differences in continuous variables were assessed using the ANOVA except in the case of TCNS in which the Kruskal-Wallis test was applied.
*The mean age for the 100 NR and R CIDP subjects was 65.3±13.7 years.
†Toronto Clinical Neuropathy Score (TCNS) is a clinical indicator of the severity of neuropathy, with 0–4, 5–8, and ≥9 indicating no, mild, and moderate to severe neuropathy. Values less than 5 are normal.
§Below the NCS mean parameter values, the range for that parameter is shown in brackets.
BMI = body mass index; DM = diabetes mellitus; PNP = polyneuropathy.
¥ Bonferroni corrected p-value for significance = 0.004.
