  • Positive values represent increasing odds of hearing loss, negative values represent decreasing odds hearing loss, and 0 represents no change in hearing loss. The constant in each model is not shown. N = 6891 for each model.

  • * Shows statistical significance at P < .05; ** shows statistical significance at P < .01.
