Sonographic Wrist Measurements and Detection of Anatomical Features in Carpal Tunnel Syndrome

Table 3

Distal and proximal cross-sectional area (CSA) of median nerve including ratio (distal/proximal CSA).

	Male			Female
	Patients	Controls	𝑃 value	Patients	Controls	𝑃 value
Distal CSA (cm^2)	0.14±0.04	0.10±0.04	0.0019	0.12±0.03	0.10±0.03	0.04
Proximal CSA (cm^2)	0.099±0.02	0.087±0.02	0.02	0.096±0.02	0.084±0.02	0.08
Ratio (distal/proximal CSA)	1.414	1.149	0.036	1.25	1.19	0.2

𝑃 values stand for statistical significance looking at CSA distal, proximal, and the ratio between patients and control in female and male.
