Agreement between neurodegeneration biomarkers. Dynamic agreement between neurodegeneration biomarkers with cutoff modification. For each biomarker pair, we calculated the agreement using all possible values in one biomarker while keeping the cutoff of the other fixed. Abbreviations: CSF, cerebrospinal fluid; AD sig, Alzheimer’s disease cortical signature; FDG PET, [18F] fluorodeoxyglucose positron emission tomography; HVa, adjusted hippocampal volume.
