Table 2.
Comparison between the values of speech audiometry (SRT and SD%) at different studied time points (initial before starting of treatment, after 1 week, after 2 weeks, and after 1 month of treatment) showing median and mean rank
| Speech audiometry | Evaluation | Median | Mean rank | Friedman test p-value |
Post hoc test (Wilcoxon signed-rank test) |
|---|---|---|---|---|---|
| Speech discrimination (SD%) | Initial | 84.0 | 1.13 | < 0.001* |
P1 < 0.001* P2 < 0.001* P3 < 0.001* P4 = 0.001* P5 < 0.001* P6 = 0.002* |
| One week | 84.0 | 2.18 | |||
| Two weeks | 88.0 | 3.03 | |||
| One month | 96.0 | 3.68 | |||
| SRT (dB nHL) | Initial | 45.0 | 4.0 | < 0.001* |
P1 < 0.001* P2 < 0.001* P3 < 0.001* P4 < 0.001* P5 < 0.001* P6 = 0.007* |
| One week | 35.0 | 2.88 | |||
| Two weeks | 35.0 | 1.83 | |||
| One month | 25.0 | 1.30 |
*Significant at p < 0.05. Pairwise comparison revealed significant differences (P < 0.05*). P1, initial versus 1 week. P2, initial versus 2 weeks. P3, initial versus 1 month. P4, 1 week versus 2 weeks. P5, 1 week versus 1 month. P6, 2 weeks versus 1 month
