Results of all enrolled subjects in OR
The fs-ABR data of all subjects (16 NH and 42 CHL ears) were analyzed,
Bland-Altman analysis showed that all dots except one were within the
95% confidence interval (CI). This dissociative dot might be caused by
the poor corporation of the patient in PTA test. The correlation between
PTA(1kHz) (X) and fs-ABR (Y) thresholds was high
(r =0.88, p <0.0001) with
Y=0.46*X+34.25(Figure3B). We also analyzed the correlation between the
PTA average threshold of 0.5/1/2kHz (PTA(0.5/1/2kHz))(X)
and the fs-ABR threshold (Y): Y=0.41*X+35.38 (r =0.84,p <0.0001) (FigureS1). Accordingly, when fs-ABR
threshold was lower than 45.58 dB SPL, PTA(0.5/1/2kHz)should be within normal hearing range.
For the CHL group in OR before surgery, Bland-Altman analysis did not
show difference between two methods (Figure3C). Linear regression
analysis also showed high correlation: fs-ABR =0.50*
PTA(1kHz)+32.17 (r= 0.66,p <0.0001) (Figure3D), and fs-ABR =
0.40*PTA(0.5/1/2kHz)+35.66 (r =0.80,p <0.0001)(FigureS1).
