Risk estimates of ipsilateral hearing loss progression among children with unilateral sensorineural hearing loss

Exposure	Comparison group	Risk estimate for progression (hazard ratio)	95% CI	P-value
Children with BCNC stenosis	Children without BCNC stenosis	2.16	(1.01, 4.66)	0.0464
Children with BCNC stenosis	Children with normal temporal bone	1.9	(0.84, 4.30)	0.123
Children with any temporal bone abnormality	Children with normal temporal bone	1.35	(0.71, 2.56)	0.367
Children with EVA	Children without EVA	0.97	(0.4, 2.34)	0.94

BCNC = Bony cochlear nerve canal

EVA = Enlarged vestibular aqueduct

CI = Confidence interval
