Data are expressed as mean (±standard deviation, SD), if not otherwise specified. The level of statistical significance was set at a p-level of 0.05. n.s. = not significant, ** = p < 0.01, n.a. = not assessed. CTS = carpal tunnel syndrome, SD = standard deviation, MN-CSA = median nerve cross-sectional area, FCR-CSA = flexor carpi radialis cross-sectional area, NTR = nerve/tendon ratio.
