Cross-section areas (CSAs) at the 8-point of the 212 carpal tunnel syndrome hands ("CTS-hands") with different nerve conduction study (NCS) severities. (A) Comparison of CSAs of the NCS minimal to NCS extreme groups with the CSAs of the NCS negative group using analysis of variance (ANOVA), followed by Scheffe's multiple comparison analysis. black triangle denoting the significant difference between the NCS minimal and NCS moderate groups; black square denoting the significant difference between the NCS negative and NCS moderate groups; black circle denoting the significant difference at w level between the NCS mild and NCS moderate groups, black diamond denoting the significant difference at o1 level between the NCS negative and NCS mild groups.
