Figure 1: (a) A statistically significant difference in the percentage of hearing loss between diabetic groups (poor vs. good glycemic control) at different frequencies (0.25– 8 kHz). *P < 0.05; **P < 0.01; ***P < 0.001. (b) Hearing thresholds in the audiogram at different frequencies between the studied groups (diabetic groups with poor vs. good glycemic control and the healthy control group). |
