Objective Assessment of Hypernasality in Patients with Cleft Lip and Palate with the NasalView System: A Clinical Validation Study

Table 1

Test-retest errors for ave and median nasalance measurement.

Measurement	Pairs of test items		Total (𝑛=157)
	Nasal sentences (𝑛=95)	Nonnasal sentences (𝑛=62)
D-Ave [%]
Mean	1.50	1.37	1.44
SD	0.99	1.15	1.05
D-Median [%]
Mean	2.84	1.66	2.37
SD	2.31	1.35	2.06

D-ave: difference of ave nasalance values between two test items; D-median: difference of median nasalance values between two test items mean: arithmetic mean; SD: standard deviation.
