OGG1 and noise induced hearing loss: In Table 3, we found that the individuals with the hOGG1 Cys/Cys genotype were more susceptible to NIHL than those who carrying the hOGG1 Ser/Ser genotype, both in the 15- to 25-year noise exposure group (adjusted OR = 1.67, 95% CI = 1.02–2.72) and in the >25-year noise exposure group (2.71, 1.16–6.36).
