Note. AgeHA = Age at Hearing Aid Fitting; 4FAHL = 4 Frequency Average Hearing Loss in the better ear; WNV = Wechsler Non-Verbal Full Scale IQ; ADisab = Additional Disabilities; MatEd = Maternal Education; Mode = Mode of Communication in early intervention; PLS-Rec = PLS-4 Receptive Language (Auditory comprehension) standard score; CDI-Rec = CDI Receptive Language (Language comprehension) developmental quotient; PPVT = PPVT-4 Receptive Vocabulary standard score; PLS-Exp = PLS-4 Expressive Communication standard score; CDI-Exp = CDI Expressive Language developmental quotient; PVC = DEAP Percent Vowel Correct (PVC) standard score; PCC = DEAP Percent Consonant Correct (PCC) standard score; PEACH = PEACH standard score.
(ln) indicates that AgeHA was transformed using the natural logarithm.
The p-value for (ln)AgeHA is for the overall test of (ln)AgeHA effects, that is, for the test that the (ln)AgeHA and (ln)AgeHA × 4FAHL coefficients are both zero.
The p-value for 4FAHL is for the overall test of 4FAHL, that is, for the test that the 4FAHL and (ln)AgeHA × 4FAHL coefficients are both zero.
For gender, the coefficient estimate is for female relative to male.
For maternal education, the first coefficient estimate is for diploma relative to school, and the second coefficient estimate is for university relative to school. The p-value for MatEd is for the overall test of MatEd, that is, for the test that both MatEd coefficients are zero.
For mode, the first coefficient estimate is for sign/mixed relative to oral only, and the second coefficient estimate is for changed or never attended relative to oral only. The p-value for Mode is for the overall test of Mode, that is, for the test that both Mode coefficients are zero.
