aβ-coefficient represents the expected difference in cognitive scores associated with a 1 year increase in age. Negative β’s indicate poorer cognitive function with increasing age.
bβ-coefficient represents the expected difference in cognitive scores associated with a 25 db increase in hearing loss (analogous to shifting from normal hearing to mild hearing loss). Negative β’s indicate poorer cognitive function with increasing hearing loss.
