A: D7. B: D30. Hearing threshold shift measurement according to 0.4R (black squares) (n = 7), 0.4 (dark grey circles) (n = 7), and 0.3 (light grey triangles) (n = 6) electrode arrays, inserted at 0.25 mm/s. Values are means ± SEM. Statistical analysis was with two-way Anova (p<0.001 at D7, and p<0.05 at D30), comparison between 0.3 and 0.4R (*p<0.05, **p<0.01, ***p<0.001), comparison between 0.4 and 0.4R ($p<0.05).
