Cognitive dedifferentiation as a function of cognitive impairment in the ADNI and MemClin cohorts


Figure 2. Sorted correlation strengths across all informative test pairs in the ADNI (n = 105) and MemClin (n = 190) datasets. Notice that inverse test scores (e.g. TMT) had been rescaled prior and that the assumption of positive manifold is slightly violated (a few negative correlations), possibly due to stochasticity.
