Figure 1: Performance on Clox 1, WAIS Digit Span, and the DRS. The change in value for each individual’s performance on each test was calculated at 3 and 6months. Values represent the mean change (± standard error of the mean). The mean performance at baseline was normalized to 0 for each test to allow comparison among tests. Values for Clox 1 differed statistically from baseline by 3 months. Values for the Digit Span did not differ statistically from baseline until 6 months. Values for the DRS did not differ statistically from baseline at either time point.
