Mean, median and standard deviation of latencies of P1, N1 and peak-to-peak amplitude of 500 Hz tone-burst evoked cVEMP from the three groups of participants.

cVEMP	Control group (n = 21)			Osteopenia (n = 24)			Osteoporosis (n = 17)
	$\overline{x}$	M	SD	$\overline{x}$	M	SD	$\overline{x}$	M	SD
P1	15.80	16.01	1.78	16.06	16.17	1.23	16.12	16.13	1.65
N1	23.81	23.77	2.95	24.26	24.23	1.90	23.69	22.92	2.48
P1N1	12.82	11.38	7.49	12.15	11.09	6.79	9.44	6.13	6.66

$\overline{x}$, mean; M, median; SD, standard deviation; P1, latency of P1 peak in milliseconds; N1, latency of N1 peak in milliseconds; P1N1, peak-to-peak amplitude of cVEMP in microvolts; cVEMP, cervical vestibular evoked myogenic potential.
