Table 6 Comparison of preoperative somatosensory-evoked potential (SSEP) waveform classification and intraoperative SSEP baseline waveform classification.

	Normal waveforms			Abnormal waveforms
	Type I	Type IIa	Type IIb	Type III	Type IV
Preoperative SSEP waveforms (n=327)	247	25	10	42	3
Intraoperative SSEP baseline waveforms (n=327)	243	20	14	47	3
Waveform classification: type I, normal waveform; type IIa, latency not exceeding mean ±2.5 SD and amplitude0.5 μV; type III, abnormal latency and amplitude; type IV, unmeasurable or absent waveform.
