Differences in categorical variables were assessed in three-group comparisons using the χ2-test, while differences in continuous variables were assessed using the analysis of variance.
Bonferroni corrected P value for significance = 0.003. CIDP, chronic immune demyelinating polyneuropathy; DM, diabetes mellitus; IVIg, intravenous immunoglobulin; PE, plasma exchange; NCS, nerve conduction study; SD, standard deviation.
