Odds ratios (OR) and 95% confidence intervals (CI) are derived from an ordinal logistic regression model with proportional odds assumption modeling for tinnitus distress in subjects with prevalent tinnitus (dependent variable) per point increase in noise annoyance (independent variable). N denotes model 3.
Model 1 was adjusted for sex.
Model 2 was additionally adjusted for age.
Model 3 was additionally adjusted for socioeconomic status.
