This study evaluates multiple machine learning models to predict clinically useful tau-PET composites, using low-cost and non-invasive inputs including clinical variables, plasma biomarkers, and structural MRI. Plasma biomarkers drive the most accurate tau-PET burden predictions, while MRI best explains hemispheric asymmetry.","DOI: 10.1002/alz.14600  \nRESEARCH ARTICLE  \nMachine learning prediction of tau-PET in Alzheimer’s disease using plasma, MRI, and clinical data  \nLinda Karlsson1  Olof Strandberg1  \n Jacob Vogel2  Ida Arvidsson3  Kalle Åström3   \n Jakob Seidlitz4, 5, 6, 7  Richard A.
