Bivariate correlation between demographic variables and speech performance scores.

r values are shown for each correlation. Age test = age at testing; CI exp = amount of experience with cochlear implant; Pre/Post = pre- or post-lingually deafened; Age implant = age at implantation; SIQ = sentence recognition in quiet; SIN = sentence recognition in noise.*p≤0.01.** p≤0.001.各组相关性均标注了相关系数r值。测试时年龄（Age test）：指受试时的实际年龄；人工耳蜗植入经验时长（CI exp）：指使用人工耳蜗的累计经验时长；聋程类型（Pre/Post）：分为语前聋与语后聋；人工耳蜗植入时年龄（Age implant）：指接受人工耳蜗植入手术时的年龄；安静环境语句识别得分（SIQ）：指安静环境下的语句识别能力评分；噪声环境语句识别得分（SIN）：指噪声环境下的语句识别能力评分。*p≤0.01，**p≤0.001。
