Odds Ratios Associated With 1 Unit Lower ABI for 1) Progression from Normal Cognition to Mild Cognitive Impairment, 2) Progression from Normal Cognition or Mild Cognitive Impairment to Dementia, or 3) Progression from Normal Cognitive Function to Mild Cognitive Impairment or Dementia or Progression from Mild Cognitive Impairment to Dementia: Odds Ratios, 95% Confidence Intervention, and P-Value After Covariate Adjustment for All Factors in Table 1.

Conversion to From Normal Cognition to Mild Cognitive Impairment*	Conversion From Normal Cognition or Mild Cognitive Impairment to Dementia	Conversion From Normal Cognition to Mild Cognitive Impairment or from Normal or Mild Cognitive Impairment to Dementia
OR=2.56 [0.89,7.35] P=0.080	OR=2.99 [0.65,13.70] P=0.157	OR=2.60 [1.06,6.37] P=0.036

Cases at follow-up: Mild cognitive impairment N=128 (8.8%)*; Probable dementia N=55 (3.4%)
