Fig. 5: Percent variance explained of individual adjustments for pairs of outcomes, with estimates shown by cohort.

Values shown are R2 with 95% credible intervals. Estimates computed from models fit on each of two cohorts: MCSA + ADRC shown in the orange circle and ADNI in a blue triangle. In the statistical analyses, each participant was a unique observation, and the number of participants varies across the comparisons based on data availability. For the MCSA + ADRC: amyloid PET SUVR with tau PET SUVR (n = 1440), amyloid PET SUVR with WMH% (n = 2383), amyloid PET SUVR with FA GCC (n = 2006), tau PET SUVR with WMH% (n = 1417), tau PET SUVR with FA GCC (n = 1119), and FA GCC with WMH% (n = 2004). For ADNI: amyloid PET SUVR with tau PET SUVR (n = 660), amyloid PET SUVR with WMH% (n = 723), amyloid PET SUVR with FA GCC (n = 572), tau PET SUVR with WMH% (n = 665), tau PET SUVR with FA GCC (n = 527), and FA GCC with WMH% (n = 575). Source data are provided as a Source Data file. * ADNI = Alzheimer’s Disease Neuroimaging Initiative, ADRC = Mayo Alzheimer’s Disease Research Center, FA GCC = fractional anisotropy in the genu of the corpus callosum, MCSA = Mayo Clinic Study of Aging, SUVR = standardized uptake value, WMH% = white matter hyperintensity volume scaled as % of total intracranial volume.
