From: Human Cochlear Histopathology Reflects Clinical Signatures of Primary Neural Degeneration
Relationship between hearing thresholds (dB HL) and total neuronal loss (% of age-based mean) does not vary significantly across cochlear length within patients with severe neural degeneration (n = 30 ears). Cochlear length analyzed in four segments (see inset). Solid lines, linear regressions per cochlear segment; shaded areas, 95% confidence intervals for slope; data points, individual observations color-coded by cochlear segment. Conditional f test with Kenward-Rogers correction for degrees of freedom shows that the slopes of these lines are significantly different from zero (p < 0.001), but not significantly different from one another (p = 0.43).
