Figure 2.

Comparison of (a) low-frequency Hearing Thresholds and (b) mid-frequency Hearing Thresholds between study groups. Adjusted means of hearing threshold in the study group were estimated from ANCOVA after adjustments for age, sex, screening center, heavy alcohol, smoking status, history of hypertension, HbA1c, and HDL-C. * Adjusted p < 0.001 versus control group in post hoc analysis. ^† Adjusted p < 0.001 versus pre-sarcopenia alone group in post hoc analysis. ^‡ Adjusted p < 0.001 versus obesity alone group in post hoc analysis. # Adjusted p < 0.001 versus pre-sarcopenic obesity group in post hoc analysis. Abbreviations: HbA1c, glycated hemoglobin; HDL-C, high-density lipoprotein cholesterol.
