Fig. 4: Interactive relationships between LC intensity and plasma markers in predicting PACC performance.

Note: A effect sizes and 95% confidence intervals of the interaction between each biomarker and the respective LC intensity cluster on PACC performance. The shaded region indicates the best model (ptau231) and this association is depicted in (B). B At values above ~15.7 pg/ml of ptau231, lower LC integrity is associated with lower PACC score.
