MAPT and metabolic dysfunction-associated steatotic liver disease: Prevalent NAFLD was not associated with β-amyloid or tau onPET. FIB-4 was significantly associated with increased rhinal tau (β = 1.03 ± 0.33, p = 0.002). FIB-4 was related to inferior temporal, parahippocampal gyrus, entorhinal, and rhinal tau and to β-amyloid deposition overall and in the inferior temporal and parahippocampal regions.
