From: Nerve excitability test and lead toxicity: a case-control study
Linear regression of the results of the NCSs, MEPs and indices of NETs to the BLL. S3 (TEh 90–100 ms) was better correlated with the BLL than the other three parameters. DL: distal latency; BLL: blood lead level; MNCV: motor nerve conduction velocity; MEP: motor evoked potential; TEh: hyperpolarization condition of threshold electrotonus
