Validation of whole-tract FA correlations, corresponding to Figure 7. Columns show the parameters of the best-fit line y = mx + c and the correlation coefficient, r, between tract FA values from subject-specific fibre bundles and those from each atlas, measured using a repeated measures correlation (Bland and Altman, 1995). Also shown is the difference between the z-transform of the correlation coefficients for the age-specific atlas and the JHU atlas, and the 95% confidence intervals (CI) for this difference. Positive differences indicate a higher correlation with the age-specific atlas. These are shown for the same-site validation data, the HBN data with FOD-based tractography, the HBN data with tensor-based tractography, and the HBN data with minimal processing and tensor-based tractography. *p < 10^-10. HBN = Healthy Brain Network; FOD = fibre orientation distribution; JHU = Johns Hopkins University.
