PPA. Positive Percent Agreement; NPA: Negative Percent Agreement; OPA: Overall Percent Agreement Figure 4 - Scatterplots and correlations of amyloid quantification values with individual biomarkers (A, C, E) and ratios (B, D, F) Correlation between SUVR values and CSF biomarkers was assessed by fitting quadratic linear models for all participants (black) and after stratifying by visual amyloid status (red and green). Shaded areas indicate 95% confidence intervals. Dashed vertical lines indicate the SUVR cutoff of 1.11 as in Landau et al. Horizontal lines correspond to cutoffs for each CSF biomarker and ratio.
