Carpal tunnel syndrome (CTS), cross sectional area distal (CSAd), cross sectional area proximally (CSAp), cross sectional area difference (ΔCSA), mean average of cross sectional area distal and proximal (CSApd), body mass index (BMI), standard deviation (SD), P value was calculated by independent t-test between two groups with 95%CI
