TABLE 6.

Normative data for subjective visual vertical (SVV) and horizontal (SVH)

Test	Metric	RI lower limit	RI upper limit	90% CI for lower limit RI	90% CI for upper limit RI
SVV	Mean error (deg)	−2.84	3.08	(−3.00) ‐ (−2.64)	2.81‐3.35
SVH	Mean error (deg)	−3.00	2.90	(−3.27) ‐ (−2.74)	2.33‐3.14

Note: The upper and lower limits of the 95% RI and 90% CI for each limit are presented. For one‐sided metrics, the limit of no interest is marked with not applicable (NA). For description of each metric see Table 2. SVV test has been performed in a total of 446 participants, on both devices, the NOTC (N = 287) and the Dx100 (N = 159). SVH test has been performed in the NOTC device only in a total of 291 participants.
