Figure 4. Lower NAA/Cr increases the risk of dementia in MCI.
Estimates of the probability of remaining free of dementia over time based on age, gender, and education -adjusted Cox models with NAA/Cr as the predictor. Estimates assume a 76 year old patient with 14.6 years of education and represent a weighted average of the curves for men and women where the weights are the proportion of men and women in our sample (63).
