In the version of this article initially published, in the legend to Extended Data Fig. 9, Extended Data Fig. 3a,b was incorrectly identified as Supplementary Fig. 4a,b, and Extended Data Fig. 6a,b was incorrectly identified as Supplementary Fig. 8a,b. The correct section of that legend is as follows: “...tau burden from Extended Data Fig. 6a,b (respectively a, and b) but also oligomeric tau levels from Fig. 3a (respectively c, and d, p = 0.057) and 2 epitopes of tau hyperphosphorylation: PHF6, from Extended Data Fig. 3b (respectively e, and f, p = 0.051) and AT8 from Extended Data Fig. 3a (respectively g, and h)...”. The error has been corrected in the HTML and PDF versions of the article.
