The distribution of Braak stages (A) and stages of concomitant LATE-NC pathology (B) did not differ between participants with PART and ADNC in our sample. However, those with relatively higher Braak stages (i.e. III-IV vs I-II) were more likely to have concomitant LATE-NC pathology (C), even in models adjusted for age and sex. In contrast, the number of concomitant ischemic vascular pathologies (tallied across infarcts, microinfarcts, and hemorrhages/microbleeds) did not differ between PART and ADNC (D), Braak stages (E), or presence of LATE-NC co-pathology (F).
