Rate of change in disc height index (∆DHI). The ∆DHI shows a significant gradual decrease over the ten-year period (p < 0.0001) (Fig. 3). An analysis of variance revealed no significant disc level and time-point interactions (p = 0.63). The ∆DHI at each level shows similar changes over ten years that did not differ significantly among the disc levels (p = 0.78)
