Efficacy of LNM (identification of 341 NARs).

	Control group	LNM group	P
Initial visual ID of RLN (%)	179/185 (96.8%)	152/156 (97.4%)	0.76
Final ID of RLN (%)	179/185 (96.8%)	156/156 (100%)	0.03
P	—	0.12	—
Initial visual ID of EBSLN (%)	73/185 (39.5%)	67/156 (42.9%)	0.51
Final ID of EBSLN (%)	73/185 (39.5%)	118/156 (75.6%)	<0.01

ID: identification; NAR: nerve at risk; LNM: laryngeal nerve monitoring; RLN: recurrent laryngeal nerve; EBSLN: external branch of the superior laryngeal nerve.
