Cognitive Aging. Multivariable linear regression models illustrating the relationship of physical (PA) and cognitive (CA) activities on models of cognitive aging across independent cohorts (UCSF and UCD). Each column represents a regression model with omnibus model fit and parameter standardized beta values *p < 0.05; **p < 0.01
