Table 2

(a) Bivariate associations between peripheral sensory systems. (b) Bivariate associations between peripheral sensory systems adjusted for age.

(a)

	Vestibular function	Proprioceptive threshold	Visual acuity	Hearing threshold
Vestibular function		−0.02 (−0.14, 0.10)	−0.13 (−0.25, −0.02)	−0.24 (−0.36, −0.13)
Proprioceptive threshold	−0.01 (−0.09, 0.07)		−0.02 (−0.14, 0.09)	0.06 (−0.06, 0.18)
Visual acuity	−1.21 (−2.1, −0.28)	−0.29 (−1.7, 1.1)		0.33 (0.22, 0.44)
Hearing threshold	−0.014 (−0.02, −0.01)	0.005 (−0.01, 0.02)	0.002 (0.001, 0.003)

Regression coefficients refer to change in the column variable associated with 1 unit change in row variable for bottom half of table. represents normalized regression coefficients corresponding to bottom half of table. 95% confidence intervals are included in parentheses. The units for the variables are vestibular function (VOR gain ratio), proprioceptive threshold (degrees), visual acuity (LogMAR), and hearing threshold (dB).
