Table 3: Odds ratio calculations for riskfactors in children with SNHL and BNH with exchange transfusion. 
 Variable  SNHL n = 15  BNH n = 87  OR 95% CI  P  Yes  Yes 
 Preterm infants  14  93%  53  61%  8.9 (1.1–71.4)  0.01  Asphyxia  2  13%  5  6%  2.5 (0.4–14.3)  0.28  Neonatal sepsis  9  60%  42  48%  1.6 (0.5–4.9)  0.40  Intraventricular hemorrhage  2  13%  2  2%  6.5 (0.8–50.5)  0.04  Amikacin exposure  7  47%  49  56%  0.6 (0.2–2.0)  0.48  Furosemide exposure  5  33%  7  8%  5.7 (1.5–21.4)  0.005 


SNHL: sensorineural hearing loss. BNH: bilateral normal hearing. n: number of cases. OR: odds ratio. CI 95%: confidence interval.
