Abbreviations: GDS, Geriatric Depression Scale; GLMM, generalized linear mixed model; HTN, hypertension; SMC, subjective memory complaint; SD, standard deviation; CI, confidence interval; MCI, mild cognitive impairment; 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.
