Note.

Multiple logistic regression models with CDR=0.5 as outcome and OME/SIT variable as predictor, adjusted for age, education, gender, and race.

Cutoffs based on 10^th percentile of total distribution of the OME/SIT variables.

Non-white race, older age, and male gender are significantly associated with 0.5 CDR global score.

Significant interactions are Fuld OME 3 trials × Age, PIR × Age, and TIR × Education.
