Group characteristic given as a total and by sub-groups based on reported tinnitus. Categorical measures given as number(percent) and continuous measures given as mean(standard deviation). P-values show statistical test for differences between sub-groups. Level of significance set to 0.05. PTA4=four-frequency pure tone average, THI=tinnitus handicap inventory, THI cat=tinnitus handicap inventory score category, HbA1c=glycated hemoglobin, LDL=low density lipoprotein, HDL=high density lipoprotein, SBP=systolic blood pressure, DBP=diastolic blood pressure, BMI=body mass index.
