Any hearing loss: FFPTA and/or HFPTA and/or LFPTA.
e, E use with caution (coefficient of variation 16.6–33.3%), population size and %, respectively.
f, F too unreliable to be published (coefficient of variation greater than 33.3%), population size and %, respectively.
DPOAE, distortion product otoacoustic emissions; FFPTA, four-frequency pure tone average over frequencies (0.5, 1, 2, and 4 kHz); HFPTA, high-frequency pure tone average over frequencies (3, 4, 6, and 8 kHz); LFPTA, low-frequency pure tone average over frequencies (0.5, 1, and 2 kHz).
*, ‡ Significantly different from estimate for reference category (P < 0.05) and (P < 0.01), respectively.
