Histograms of mesial temporal and entorhinal cortex SUVR. Tau burden in a mesial temporal composite (Me) and the entorhinal cortex as measured by tau PET SUVR. A The red dashed line separates the cohort by the 95% percentile Me SUVR (top 5% vs lower 95%), while the black dashed line separates the cohort by the 90% percentile Me SUVR (top 10% vs lower 90%); B the black dashed line represents a visually derived threshold used to discriminate higher (EC+) from lower entorhinal SUVR (EC−)
