The chi-squared test was used to compare the prevalence of minimal hearing loss and its subgroups according to sex. An asterisk (*) indicates a significant difference (P < 0.05).
USHL: unilateral sensorineural hearing loss; BSHL: bilateral sensorineural hearing loss; HFSHL: high-frequency sensorineural hearing loss
