Fig. 4.

Changes of ABR wave 4 amplitudes and latencies after cisplatin 4 × 1 treatment. a–d ABR wave 4 amplitudes were measured before (solid lines; baseline) and after cisplatin (n = 10) or saline (n = 6) administration (dashed lines). Two-way ANOVA revealed no differences in wave amplitudes between the treated (cisplatin) and control (saline) across all four frequencies. e–h ABR wave 4 latencies were measured and the latency at 40 kHz was longer in the cisplatin group compared with saline group. *p < 0.05. Data shown are the means ± 1 SEM
