Table 3. Correlations of Change.

Correlations between change in AB40 and change in each other indicated variable as estimated by multivariate outcome mixed-effect models. We estimated the lower and upper bounds of the 95% confidence intervals by 1,000 simulations. Correlations that are significantly different form zero are indicated in bold.
