Fig. 3: Tau-PET values in screened-in versus screened-out patients based plasma pTau217.
From: A blood-based biomarker workflow for optimal tau-PET referral in memory clinic settings
This figure shows the tau-PET levels according to plasma pTau217 levels based on different screening strategies (Sensitivities; left: 90%, middle: 95%, right: 97.5%). The y-axis dots indicate the standardized uptake value ratio (SUVr) based on a Braak I-IV meta-temporal composite region. The x-axis indicates whether patients had abnormal values according to the cutoff for each strategy. Boxplots represent the median, interquartile range (IQR), and range to smallest or largest value no further away from 1.5*IQR. Results for BioFINDER-2 (n = 402) are presented in the top row, and in the bottom row for TRIAD (n = 160). Source data are provided as a Source Data File. PET positron emission tomography, pTau phosphorylated tau, SUVr standardized uptake value ratio.
