Parameters of nerve conduction studies
| Variables | Total cohort | Patients with DPN | Patients without DPN | P |
|---|---|---|---|---|
| Standard nerve conduction study | ||||
| Sural nerve conduction velocity (m/s) | 45.0 ± 5.4 | 44.5 ± 5.0 | 45.7 ± 5.2 | 0.3379 |
| Sural nerve action potential (μV) | 7.1 ± 5.5 | 5.7 ± 3.6* | 8.9 ± 5.9 | 0.0003 |
| Point‐of‐care device | ||||
| Sural nerve conduction velocity (m/s) | 48.4 ± 6.4 | 47.3 ± 5.9 | 48.8 ± 5.9 | 0.2864 |
| Sural nerve action potential (μV) | 9.6 ± 5.7 | 8.6 ± 5.7* | 10.8 ± 5.9 | 0.1159 |
Data are presented as mean ± standard deviation. The participants whose action potential was not detected were excluded from calculation of mean values. *P < 0.05 versus patients without diabetic polyneuropathy (DPN). P, P‐value between patients with diabetic polyneuropathy and without diabetic polyneuropathy.
