In 16 patients with carpal tunnel syndrome and 32 matched controls, evaluation of the median nerve was performed by the cross-sectional area at wrist level and wrist\u2013forearm ratio. This study found statistically significant differences between patients and controls by both methods, and both showed high specificity and positive predictive values.
