Cell with dotted outline indicate the AAO-HNSF PTA asymmetry cutpoint. Gray highlighted cells indicate cutpoints with both greater sensitivity and specificity than the AAO-HNSF PTA asymmetry cutpoint.
PTA indicates pure-tone average; SNR, signal-to-noise ratio; VS, vestibular schwannoma; WRQ, word-recognition in quiet.
