Inflammatory and Immune Proteins in Umbilical Cord Blood: Association with Hearing Screening Test Failure in Preterm Neonates

Table 4

Risk factors associated with newborn hearing screening test failure according to logistic regression analyses.

Risk factors	Risk of failure in the newborn hearing screening test
	Adjusted for umbilical cord plasma C3a		Adjusted for all variables in the model
	OR (95% CI)		OR (95% CI)
Umbilical cord plasma IL-6 (pg/mL)	1.031 (1.000–1.063)	0.050	1.004 (0.960–1.050)	0.859
Funisitis	3.827 (1.197–12.233)	0.024	2.683 (0.694–10.375)	0.153
Elevated blood CRP levels (>5 mg/L) in immediate postnatal period	6.515 (1.814–23.398)	0.019	3.503 (0.524–23.404)	0.196
Umbilical cord plasma C3a (μg/mL)			0.875 (0.780–0.982)	0.023

OR: odds ratio; CI: confidence interval; IL: interleukin; CRP: C-reactive protein.
