CTS = carpal tunnel syndrome; DPN = diabetic polyneuropathy; BH = body height; BW = body weight; BMI = body mass index; M = male; F = female.
The data shown are mean ± standard deviation (SD) (median, range).
^* = 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.
