Mean ± SE audiometric hearing threshold at study entry (a) and end point (b) and the hearing gain (c) among four cohorts after PSM. (*P < 0.05 vs. USSHL; †P < 0.05 versus Se-BSSHL; ‡P < 0.05 versus Si-BSSHL). USSHL: Unilateral sudden sensorineural hearing loss with normal hearing in the contralateral ear; USSHLwCHL: Unilateral sudden sensorineural hearing loss with preexisting contralateral hearing loss; Se-BSSHL: Sequential bilateral sudden sensorineural hearing loss; Si-BSSHL: Simultaneous bilateral sudden sensorineural hearing loss; SE: Standard error of the mean.
