Values Related to Mean, SD and Range in Patients and Control Group

Note.-CSAa = cross sectional area (CSA) of median nerve proximal to tunnel inlet, CSAb = CSA at pisiform bone level, CSAb-a = area difference between CSAb and CSAa, % area = percentage of area increase of CSAb according to CSAa, D-L = largest diameter of median nerve at tunnel, D-S = diameter perpendicular to D-L, Flattening ratio = D-L/D-S, SD = standard deviation
