Comparing mean labyrinthitis ossificans grade by meningitis^{^a}

	Mean (SE)		P Value
	No Meningitis (n = 52)	Meningitis (n = 6)	P Value
Apical turn of cochlea^{^b}	0.84 (0.23)	0.50 (0.71)	.657
Middle turn of cochlea^{^b}	0.88 (0.23)	0.72 (0.70)	.829
Basal turn of cochlea^{^b}	1.11 (0.24)	0.81 (0.73)	.697
Vestibule	0.63 (0.18)	0.04 (0.55)	.317
Lateral semicircular canal	1.77 (0.19)	1.91 (0.56)	.806
Posterior semicircular canal	1.22 (0.22)	1.96 (0.65)	.296
Superior semicircular canal	1.0 (0.22)	0.94 (0.64)	.925

↵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 (51 without meningitis and 6 with meningitis).
