Fig. 1. The concentrations of plasma NfL for different diagnostic and controls groups in the KCL and Lund cohorts.
Plasma neurofilament light (NfL) in different diagnostic groups; KCL (A n = 805) and Lund (B n = 1464) cohorts. For each plot, the horizontal bar shows the median, and the upper and lower boundaries show the 25th and 75th percentiles, respectively. Source data are provided as a Source Data file. KCL Cohort—AD Alzheimer’s disease (n = 102), ALS amyotrophic lateral sclerosis (n = 50), CU Aβ− cognitively unimpaired without Aβ pathology (n = 130), CU Aβ+ cognitively unimpaired with Aβ pathology (n = 28), CBS/PSP corticobasal syndrome and progressive supranuclear palsy (n = 19), depression (n = 37), DS Down syndrome (n = 29), DSAD Down syndrome Alzheimer’s disease (n = 12), EOAD early-onset Alzheimer’s disease (n = 59), FTD frontotemporal dementia (n = 54), MCI Aβ− mild cognitive impairment without Aβ pathology (n = 55), MCI Aβ+ mild cognitive impairment with Aβ pathology (n = 31), PD Parkinson’s disease (n = 140), PDD/DLB Parkinson’s disease dementia and dementia with Lewy bodies (n = 59). Lund Cohort—AD Alzheimer’s disease (n = 134), CU Aβ− cognitively unimpaired without Aβ pathology (n = 273), CU Aβ+ cognitively unimpaired with Aβ pathology (n = 103), CBS/PSP corticobasal syndrome and progressive supranuclear palsy (n = 24), EOAD early-onset Alzheimer’s disease (n = 23), FTD frontotemporal dementia (n = 150), MCI Aβ− mild cognitive impairment without Aβ pathology (n = 115), MCI Aβ+ mild cognitive impairment with Aβ pathology (n = 165), MSA multiple system atrophy (n = 29), PD Parkinson’s disease (n = 171), PDD/DLB Parkinson’s disease dementia and dementia with Lewy bodies (n = 46), SCD Aβ− subjective cognitive decline without Aβ pathology (n = 134), SCD Aβ+ subjective cognitive decline with Aβ pathology (n = 75), VaD vascular dementia (n = 22).
