Abbreviations: GLMM, generalized linear mixed model; SD, standard deviation; SE, standard error; CI, confidence interval; MoCA, Montreal Cognitive Assessment.

Note: Model coefficients are in log odds. 95% CIs for model coefficients are in log odds. Serial subtraction and abstraction scores centered at means. There was zero variance for study (i.e., ADNI or NACC) in model; it was excluded as a random effect because the model only converged after it was removed.
