  1. The 0 mm3 corresponds to the original data. We also show the 95% confidence interval of the mean SDI. Statistical comparisons between the different thresholds was done using the two-sided paired Wilcoxon rank test141 with correction for multiple comparisons.
  2. †Denotes statistical significance at an α level of 0.001 when comparing to the 0 mm3 threshold.
  3. ‡Denotes statistical significance at an α level of 0.001 when comparing to the 1 mm3 threshold.
