Normative modeling in clinical cohorts.
Reference brain charts were transferred to several clinical samples (described in (A)). Patterns of extreme deviations were summarized for each clinical group and compared to matched control groups …

Evaluation metrics across all test sets.
The distribution of evaluation metrics in four different test sets (full, mQC, patients, and transfer, see Materials and methods) separated into left and right hemispheres and subcortical regions, …

Comparison of the explained variance in cortical thickness across the different test sets.
The patterns appear to be robust and consistent across the different test sets.

Example of the online interactive visualizations created to help interpret the evaluation metrics.
This interactive figure was created for each evaluation metric (EV, MSLL, skew, and kurtosis) and all test sets (full controls, mQC controls, clinical, and transfer).
