The spearman correlation between the executive function and the VDS score and between the memory function and the ADS score for the full patient group (80 subjects) is shown in Figs. 8A and 8B, and for a subset of the subjects (55 subjects) in Figs. 8C and 8D. The selected subset of subjects for Figs. 8C and 8D are those with matching clinical and biomarker-based cluster diagnosis. In this subset of subjects there is stronger correlation with cognitive function. This is an example of how cluster diagnosis can be used to identify a more homogenous group of subjects with well characterized properties.
