Fig. 2. — Distribution of hearing loss grades in the genetic cochlear implant cohort. A, Distribution of preoperative hearing loss grades for all implanted ears (n= 123). B, Distribution of preoperative hearing loss grades for all nonimplanted ears (n=29). NH indicates normal hearing (−10.0 to 19.9 dB HL), MHL mild hearing loss (20.0 to 34.9 dB HL), MOHL moderate hearing loss (35.0 to 49.9 dB HL), MSHL moderately severe hearing loss (50.0 to 64.9 dB HL), SHL severe hearing loss (65.0 to 79.9 dB HL), PHL profound hearing loss (80.0 to 94.9 dB HL), and CHL complete or total hearing loss (≥95.0 dB HL). Classification follows the recommendations of the Global Burden of Disease (GBD) Expert Group on Hearing Loss (Global Burden of Disease Hearing Loss Expert Group et al. 2013; Olusanya et al. 2019). Percentage values for different hearing loss grades are shown below bars.
