In the table, coefficient refers to the difference in hearing level (at each frequency) for every 1 unit change in the factor examined (independent variable, e.g., age, severity). In the model, only age at diagnosis at 500 Hz was significant, i.e., for each month later age of diagnosis, there was a very slight improvement in hearing. For the etiologic (categorical) factors, the coefficient represents the amount of change in hearing level when the etiologic factor is not present vs. present. In the model, no coefficients were statistically significant, i.e., no factors were associated with a difference in hearing level at any frequency.
