Figure 7.

Box plots showing distributions of annual rate of change in Executive Function as measured by the sum of the predicted change for the diagnostic group and the person specific random deviation from this predicted value. The box demarcates the range from the 25^th to the 75^th percentile of the distribution, the line in the middle of the box is the 50^th percentile, the lower horizontal line is at the 10^th percentile, and the upper horizontal line is at the 90^th percentile. Dem-D = Dementia at first and at last evaluation, MCI-D = MCI at first evaluation, Dementia at last, MCI-MCI = MCI at both evaluations, MCI-N = MCI at first and Normal at last, Norm-MD = Normal at first evaluation, MCI or Dementia at last, Norm-N = Normal at first and last evaluations.
