Associations of the cerebrospinal (CSF) biomarker levels with cognitive domain scores in early-stage Parkinson′s disease patients. Data are standardized β coefficients from linear regression models, adjusted for age, gender, and level of education. Color intensity is based on the standardized β coefficients. Abbreviations: CSF, cerebrospinal fluid. t-α-syn, total α-synuclein. p-α-syn, phosphorylated α-synuclein. NfL, neurofilament light chain. Aβ42, amyloid-β42. t-tau, total tau. p-tau, phosphorylated tau. sβ, standardized β-coefficient.
