Figure 1
Comparison of longitudinal change of speech perception scores between the GD and GUD groups. There was no significant difference in speech perception scores between two groups at any time point, from baseline to 12 months (as seen through Supplement Fig. 1). The speech perception scores significantly increased within 3 months after cochlear implantation, and subsequently reached a plateau at the 6-month postoperative evaluation, regardless of the group. The degree of reflection of the speech perception scores at 3 months was more than 0.8 in both the GD and GUD groups. The speech perception score at 12 months was almost the same as the 6-month score.
