Table 2 Correlations among cortical flortaucipir SUVr and Histelide estimates of Ptau and Aβ tissue concentrations at autopsy

From: Comparison of regional flortaucipir PET with quantitative tau immunohistochemistry in three subjects with Alzheimer’s disease pathology: a clinicopathological study

  Model 1 (no adjustment) Model 2 (adjusted for case) Model 3 (adjusted for case and other pathology
  Pearson r p Value Pearson r p Value Pearson r p Value
Ptau vs SUVr 0.81 p < 0.0001 0.81 p < 0.0001 0.73 p < 0.0001
Aβ vs SUVr 0.61 p < 0.0001 0.52 p < 0.0001 0.01 p = 0.9302
Ptau vs Aβ 0.66 p < 0.0001     
  1. Model 1: No adjustment; Model 2: partial correlation by adjusting for case ID; Model 3: partial correlation by adjusting for case ID, and the other pathology. For example, the correlation between PHF tau and SUVr was adjusted for case ID and Aβ1-42
