In the Original Investigation by Meyer et al, titled “Characterization of Alzheimer Disease Biomarker Discrepancies Using Cerebrospinal Fluid Phosphorylated Tau and AV1451 Positron Emission Tomography,” published online January 21, 2020,1 there were errors in the Abstract, the text of the article, Figures 1 and 2, and in the author affiliations list. In the “Main Outcomes and Measures” section of the Abstract, the first sentence should read “We compared tau-positive vs tau-negative groups as indicated by either modality or demographic and clinical variables, amyloid β–PET burden, and flortaucipir-PET binding across Braak stage–related ROIs.” In the “PET Image Processing” subsection of the Methods, both instances of the S in “FreeSurfer” should be capitalized. In the final sentence of the first paragraph of the CSF Measurements subsection of the Methods, “Cobas” should be capitalized. In Figure 1, the R2 value should be 0.26. In Figure 2, panel A should be labeled “APOE ε4 carriers,” panel C should be labeled “Aβ+ individuals” and have PET− in superscript in all instances, and the y-axis for panel D should be labeled “Global Florbetapir SUVR.” Finally, in the author affiliations, Dr Pichet Binette’s name should be listed as “Pichet Binette” rather than “Binette.” This article was corrected online.
