Canonical correlation analysis derived a multivariate plasma pathology index and cognitive composite based on memory and language performance. The residual phenotype was defined as the deviation between observed cognition and cognition expected from plasma pathology burden. Clinical correlates and longitudinal trajectories were evaluated using regression and mixed-effects models. Biological validity was assessed by examining associations with amyloid-\u03b2 and tau positron emission tomography measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The first canonical correlation between plasma markers and cognition was significant (r\u2009=\u20090.610, permutation p\u2009&lt;\u20090.001).
