Improvement on the compound measure of mathematics. (a) Mean and standard error of the mean (sem) of the improvement for the 4 training groups (typically developing sample only); (b) interaction between WM_bl and WMT on math improvement, the plot reports the mean and sem of the delta (i.e. the difference) between Math_post and Math_bl; (c) interaction between Math_bl and NLT on math improvement; (d) surface and contour plots showing math improvement based on continuous interpolation of WM_bl and Math_bl in the WMT/Read and NLT/Read groups. Measured points are represented by the black dots.
