Associations between CSF sPDGFRβ with CSF/plasma ratios of Aβ40, Aβ42 and T-tau in CSF/plasma cohort. A-C There were no significant relationships of Aβ40, Aβ42 and T-tau between CSF and plasma. D-E CSF sPDGFRβ were positively associated with CSF/plasma ratios of Aβ40, Aβ42 and tTau. The best-fit linear regression line is shown and 95% confidence intervals are superimposed. CSF, cerebrospinal fluid; T-tau, total-tau; sPDGFRβ, soluble platelet-derived growth factor receptor β; ns, no significance. *p<0.05, ** p<0.01, *** p<0.001
