↵a Two-sample t test P values are for comparisons among SNHL, CHL, mixed HL, or unknown-hearing ears and normal-hearing ears divided by all, male, or female.
↵b Statistically significant differences (P < .01).
↵c For the comparison of male and female CHs, multivariate linear regression controlling for age and ICW was used.
