| SRAR + BT (15V as cut-off) | SRAR + BT (25V as cut-off) | SRAR + F wave | SRAR + F wave + BT (15V as cut-off) | SRAR + Lt LL F wave | SRAR + Lt LL F wave + BT (15V as cut-off) | |
|---|---|---|---|---|---|---|
| Sensitivity | 78.6% | 50% | 78.6% | 71.4% | 71.4% | 64.3% |
| Specificity | 64.7% | 97.1% | 88.2% | 91.2% | 94.1% | 94.1% |
SRAR - Sural Radial Amplitude Ratio; BT - Biothesiometer; Lt LL - Left Lower limb
