Fig. 1: Correlation between performance at T1 and absolute cognitive change scores (abs∆).

The first figure (on the left side) shows the correlation between the performance at T1 and the absolute change score for processing speed (r = −0.679, p < 0.001). The second figure (on the right side) shows the correlation between the performance at T1 and the absolute change score for working memory (r = −0.511, p < 0.001).
