Multivariate linear regression models of the association between vestibular function and triangle completion task performance in all participants.a

Angle of deviation (°) |
|||
|---|---|---|---|---|
| Unadjusted β (95% CI) | Adjusted β (95% CI) | Unadjusted β (95% CI) | Adjusted β (95% CI) | |
| cVEMP response | ||||
| Abnormal cVEMP response | 31.3 (15.2, 47.4) | 18.2 (1.2, 35.1) | 11.7 (6.1, 17.3) | 9.2 (3.0, 15.5) |
| cVEMP amplitude of the better ear (μV) | −5.4 (−13.9, 3.1) | −9.6 (−20.4, 1.2) | −0.5 (−3.1, 2.1) | −2.1 (−5.3, 1.1) |
| VOR gain | ||||
| Abnormal VOR gain | 27.4 (−0.5, 55.1) | 26.0 (0.2, 51.8) | 11.2 (1.2, 21.2) | 10.8 (0.9, 20.7) |
| VOR gain of the better-hearing ear | −14.7 (−69.6, 40.1) | −38.3 (−92.6, 16.0) | −11.0 (−36.8, 14.8) | −15.4 (−42.8, 12.1) |
| cVEMP and VOR function | ||||
| Concurrent cVEMP and VOR abnormality | 33.5 (17.4, 49.7) | 25.3 (6.2, 44.4) | 16.3 (9.4, 23.1) | 18.1 (10.1, 26.2) |
aModels were adjusted for demographic covariates (age, sex, race/ethnicity). An abnormal cVEMP response includes unilaterally or bilaterally absent cVEMP. Likewise, an abnormal VOR gain includes unilaterally or bilaterally abnormal VOR gain value (<0.8 or >1). Statistically significant regression models are bolded.
cVEMP, cervical vestibular-evoked myogenic potential; VOR, vestibulo-ocular reflex; 95% CI, 95% confidence interval.
