Overlap of plasma biomarker distribution between MCI and NC group with various eGFR levels. a Profile of plasma biomarker levels and neuropsychological test scores between MCI_high eGFR and NC_medium eGFR groups. b Profile of plasma biomarker levels and neuropsychological test scores between MCI_medium eGFR and NC_low eGFR groups. c Profile of plasma biomarker levels and neuropsychological test scores between MCI_medium eGFR and NC_low eGFR groups. The density plots show the distribution of plasma biomarker levels in different cognition and eGFR groups. The box plot showed the neuropsychological test scores in different cognition and eGFR groups. Abbreviations: NC, normal control; MCI, mild cognitive impairment; NfL, neurofilament light chain; P-tau181, tau phosphorylated at threonine 181; eGFR, estimated glomerular filtration rate; MMSE, Mini-Mental State Examination
