aChildren, prelingual severe to profound sensorineural hearing loss, simultaneous bilateral cochlear implantation.
bThe x-axis represents the willingness-to-pay threshold, and the y-axis represents the probability that the intervention is cost-effective. The dotted lines highlight the probability that bilateral cochlear implantation is cost-effective at willingness-to-pay thresholds of $50,000 (63.64%) and $100,000 (68.86%).
