Figure 1 Relation between PTA and ASSR thresholds . X-axis represents mean pure-tone thresholds and Y-axis represents mean ASSR thresholds. Mean hearing thresholds defines averaged thresholds for four frequencies (0.5k Hz, 1 kHz, 2 kHz, and 4 kHz). Results of scatter plots for unaffected ear is shown in black diamond (◊). Hearing thresholds of affected ear for SBASSR group, WASSR group, and exclusion are shown in blue circle (○), red squared (□), and black triangle (∆), respectively. PTA: pure tone audiometry; ASSR: auditory steady-state response; 4FA: four frequencies (0.5, 1, 2, and 4 kHz); SBASSR: similar or better ASSR: WASSR: worse ASSR
Figure 2 Hearing outcome between SBASSR and WASSR groups . Mean pure-tone thresholds defines averaged thresholds for four frequencies (0.5, 1, 2, and 4 kHz). Error bar means standard deviation. The asterisk (*) indicate statistically significant difference in multiple comparison test. PTA: pure-tone audiometry; WRS: word recognition scores; ns : not significant
