Abbreviations: GDS, Geriatric Depression Scale; GLMM, generalized linear mixed model; HTN, hypertension; SMC, subjective memory complaint; SD, standard deviation; SE, standard error; CI, confidence interval; MoCA, Montreal Cognitive Assessment.
Notes: Model coefficients are in log odds. 95% CIs for model coefficients are in log odds. Age and adjusted GDS centered at respective means. Study is either ADNI or NACC.
