Demographic and Clinical Data by EDX (NCS) Diagnosis.
| Demographic or Parameter | Positive NCS | Negative NCS | Statistical significance |
|---|---|---|---|
| No. of pt. hands | 330 | 72 | |
| Mean age | 54.4 ± 0.7 | 42.7 ± 1.7 | P < .001 |
| Sex (male) | 97 (29%) | 15 (21%) | P = .14 |
| Height, in | 65.5 ± 0.2 | 64.9 ± 0.4 | P = .26 |

| CTS-6 score | 14.7 ± 0.3 | 13.9 ± 0.7 | P = .33 |
| US CSA, mm2 | 11.6 ± 0.2 | 8.2 ± 0.3 | P < .001 |
Note. EDX = electrodiagnostic testing; NCS = nerve conduction studies; BMI = body mass index; CTS = carpal tunnel syndrome; CSA = cross-sectional area; US = ultrasonography; Bold faces states that the significance is p < 0.001.
