Comparing mean labyrinthitis ossificans grade by sickle cell disease^{^a}

	Mean (SE)		P Value
	No Sickle Cell Disease (n = 51)	Sickle Cell Disease (n = 7)	P Value
Apical turn of cochlea^{^b}	0.79 (0.24)	0.91 (0.65)	.858
Middle turn of cochlea^{^b}	0.89 (0.23)	0.67 (0.63)	.738
Basal turn of cochlea^{^b}	1.15 (0.24)	0.50 (0.65)	.349
Vestibule	0.63 (0.18)	0.09 (0.50)	.316
Lateral semicircular canal	1.84 (0.19)	1.40 (0.51)	.422
Posterior semicircular canal	1.32 (0.22)	1.11 (0.60)	.747
Superior semicircular canal	1.09 (0.22)	0.37 (0.60)	.261

↵a LO grade for each structure within the membranous labyrinth is reported stratified by risk factor. P value is from a mixed-effects model.
↵b Analysis is based on 57 ears (50 with no sickle cell disease and 7 with sickle cell disease).
