Table 6 Multivariate logistic regression model with outcome as conversion toAlzheimer's disease (AD) from mild cognitive impairment (MCI) within 24 monthsfrom baseline

From: Modeling the heterogeneity in risk of progression to Alzheimer's disease acrosscognitive profiles in mild cognitive impairment

Explanatory variables B Wald test P-value Exp (B)
APOE4 0.623 0.024 0.536
Episodic memory level 2 -1.445 0.001 0.236
Perceptual motor speed -0.926 0.009 0.396
Intercept 1.193 0.000 3.298
  1. Dependent variable value of 1 indicates that a subject has converted to AD fromMCI within 24 months of baseline. Binary variable Apolipoprotein (APOE)4 = 1indicates that the subject has at least one APOE4 allele and higher risk forconversion. Larger probability values of relatively high performance indicatelower risk for conversion.
