Figure 1 Threshold shift (mean ± standard error) of the auditory brainstem response at different frequencies of noise-exposed guinea pigs [CMV+ group (dashed line): n = 4; CMV− group (solid line): n = 5). Asterisks indicate significant differences between the groups (P < 0.05). CMV, cytomegalovirus.
