Group I: Normal hearing ears from infants; Group II: Sensorineural hearing loss ears from infants; Group III: Normal Hearing ears from adults.
n = number of ears.
a, b, c, dIndependent t-test was used to compare the P13 and N23 latencies and P13-N23 interval of BCV-cVEMP between Group I and II, and P13 latency between Group I and III.
pa = 0.665, t = 0.435; pb = 0.925, t = 0.094; pc = 0.806, t = 0.247; pd < 0.001, t = 5.629.
e, fMann-Whitney U-test was used to compare the N23 latency and P13-N23 interval of BCV-cVEMP between Group I and III. Pe = 0.018, z = 2.359; Pf = 0.110, z = 1.599.
SD, Standard deviation; IQR, interquartile range.
