Risk of incident Alzheimer's Dementia: Results from hierarchically formulated multivariate Cox proportional hazard regression models.

Note. M2LL of the Intercept model = 830.6. Details of the modeling process are given in the methods section. The HR for the CERAD-DR is below one as it represents the HR for a one unit increase in CERAD-DR scores (i.e. for better memory performance). Lower CERAD-DR scores are therefore associated with a higher risk of developing incident AD. B = Beta-Coefficient of the predictor, CI = Confidence Interval, CERAD-DR = Delayed Recall of the Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Assessment Battery, HR = Hazard Ratio, M2LL = Minus-Two-Log-Likelihood, MC = Memory Concerns, SE = Standard Error for B.
