TABLE 3.

Generalized multiple linear regression models for performance in auditory processes (SIN, speech in noise; DD, dichotic digits; SSW, staggered spondaic words; FP, frequency pattern; GiN, gap in noise) for both ears (RE, right ear; LE, left ear).

Independent variables included the composite scores derived from the exploratory factor analyses (hearing loss, auditory nerve, midbrain, and cognition), gender, years of education (schooling), and age. Pseudo-R-squared (R²) measures are shown for each regression when empty was non-significant.

SINRE, speech in noise right ear, correct answers; SINLE, speech in noise left ear, correct answers; DDRE, dichotic digits right ear, correct answers; DDLE, dichotic digits left ear, correct answers; SSWRE, staggered spondaic words right ear, total number of errors; SSWLE, staggered spondaic words left ear, total number of errors; FFRE, frequency pattern right ear, correct answers; FPLE, frequency pattern left ear, correct answers; GIN, gap in noise, minimum time gap detected; QB, quasi binomial; G, gamma; DF, degree of freedom.

*p < 0.05; **p < 0.01; ***p < 0.001.

Bold numbers are used to highlight statistically significant values.
