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 ACS-cVEMP between Group I and II, and between Group I and III.
pa = 0.866, t = 0.170; pb = 0.190, t = 1.335; pc = 0.252, t = 1.163.
pd = 0.016, t = 2.474; pe < 0.001, t = 5.816; pf < 0.001, t = 5.283.
SD, Standard deviation; IQR, interquartile range.
