  1. Abbreviations: CSA cross section area, D at outlet of carpal tunnel, W at the wrist crease.
  2. P value was calculated by one-way ANOVA with post-hoc comparison:
  3. α = CTS-hands vs. C-hands, p = 0.007; DM-CTS-hands vs. C-hands, p = 0.012.
  4. β = CTS-hands vs. C-hands, p < 0.001; DM-CTS-hands vs. C-hands, p < 0.001; CTS-hands vs. DM-hands, p = 0.019; DM-CTS-hands vs. DM-hands, p = 0.014.
