* = p < 0.05 (significant difference among the normal control, idiopathic, diabetic and DPN CTS hands) by the Kruskal-Wallis test.

 = a comparison of the sex difference and symptom duration among the control, idiopathic, diabetic and DPN CTS hands by the Chi-Square test.

 = a comparison of the BH between the control and the idiopathic CTS hands by the Mann–Whitney U test showed no significant difference.
