Note. The probability (p) of the corresponding distribution not being Gaussian (two-tailed, chi-squared test for goodness-of-fit) is shown, and the number of participants for whom each predictor was measured. PTT = pure tone threshold; ULL = uncomfortable loudness levels; SRT = speech reception threshold; HLOHC = outer hair cell loss; HLIHC = inner hair cell loss; BMCE = basilar membrane compression exponent; DPOAE = distortion product otoacoustic emission; BMLD = binaural-masking level difference; FMDT = frequency-modulation detection threshold; FMRR = forward-masking recovery rate; TI = temporal integration; REIG = real-ear insertion gain; SSQ = speech, spatial, and qualities; SIIQ = speech intelligibility index in quiet; COSI = client-oriented scale of improvement; IOI-HA = international outcome inventory for hearing aids.
