Table 3 Significant predictor variables for motor evoked potential (MEP) latency by mapped muscle

From: The variability of motor evoked potential latencies in neurosurgical motor mapping by preoperative navigated transcranial magnetic stimulation

Muscle Predictors p
APB MEP latency (mu) (n = 197) Plus gender <0.001
Plus AED 0.012
Plus rMT 0.008
ADM MEP latency (mu) (n = 192) Plus gender 0.001
Plus AED 0.016
Plus tumor side 0.009
FCR MEP latency (mu) (n = 157) Plus gender <0.001
Plus AED 0.012
Plus tumor location 0.016
  1. This table shows the predictor variables for MEP latencies that were statistically significant. In this context, common factors (gender and antiepileptics = AED) and muscle-specific factors (resting motor threshold = rMT, tumor side, tumor location) were revealed for abductor pollicis brevis muscle (APB), abductor digiti minimi muscle (ADM), and flexor carpi radialis muscle (FCR)
