Fig. 3From: Brain-derived nerve growth factor in the cochlea – a reproducibility studyAveraged final thresholds at day 60 with all frequencies included. The mean difference in ABR thresholds for BDNF-treated ears (60 were 60+/− 23 dB) versus saline-treated ears (71 +/− 20 dB) was significant (p = 0.034). The mean difference was 11 dB, which is less than the increase in threshold resulting from the intracochlear injectionBack to article page
