Fig. 2From: Plasma neurofilament light as a potential biomarker of neurodegeneration in Alzheimer’s diseaseUnadjusted neurofilament light chain (NfL) concentrations in the three diagnostic categories. A borderline insignificant (p = 0.11 after Scheffe correction) tendency was observed towards higher concentrations in Alzheimer’s disease dementia (ADD) compared with mild cognitive impairment Alzheimer’s disease (MCI-AD). The green horizontal line represents the cutoff at the maximized Youden index (25.7 pg/mL), leading to the unadjusted diagnostic accuracy of 82% in the setting of controls versus AD (MCI-AD and ADD). *p < 0.05Back to article page
