Clinical and electrodiagnostic features of 67 CIDP-DM and 67 CIDP+DM subjects.

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 134 CIDP-DM and CIDP+DM subjects was 65.8±13.5 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. For the deep tendon reflex (DTR) segment of the TCNS, the normal value is 0. For TCNS, median and interquartile range (IQR) are shown and IQR are compared.
‡The mean HbA1c, indicating the percentage of haemoglobin A1c, for 71 of the 134 CIDP-DM and CIDP+DM subjects was 7.1±1.9%.
§Below the NCS mean parameter values, the range for that parameter is shown in brackets.
BMI = body mass index; DM = diabetes mellitus; PNP = polyneuropathy; VPT = vibration perception threshold; DTR = deep tendon reflexes of the lower limb; NR = non-recordable.
¥ Bonferroni corrected p-value for significance = 0.001.
