	Mean (SE)		P Value
	No Risk Factor (n = 11)	Any Risk Factor (n = 47)	P Value
Apical turn of cochlea^{^b}	0.33 (0.49)	0.92 (0.24)	.280
Middle turn of cochlea^{^b}	0.22 (0.47)	1.03 (0.24)	.132
Basal turn of cochlea^{^b}	0.35 (0.48)	1.26 (0.24)	.095
Vestibule	0.01 (0.37)	0.71 (0.19)	.097
Lateral semicircular canal	1.29 (0.40)	1.90 (0.19)	.181
Posterior semicircular canal	0.65 (0.46)	1.44 (0.23)	.136
Superior semicircular canal	0.45 (0.47)	1.15 (0.23)	.190

↵a LO grade is reported per membranous labyrinth structure based on patients with an identified LO risk factor compared with those without a risk factor. P value is from a mixed-effects model.
↵b Analysis is based on 57 ears (11 with no condition and 46 with a condition).
