From: The subtleties of cognitive decline in multiple sclerosis: an exploratory study using hierarchichal cluster analysis of CANTAB results

Fig. 5

Dendrograms from a cluster analysis of healthy control subjects and multiple sclerosis patients based on their performance on Mini-Mental State Examination (MMSE) and Word List Recognition (WLR). The Euclidean distance in this figure (near 50) highly contrasts with the analysis with only CANTAB battery (near 4000). Three subjects with optical neuritis move from group 2 to group 1. Some MS patients in group 2 of the previous analysis (CANTAB) migrated to group 1 in this analysis, diminishing the size of group 2. Finally, Mini-Mental State Examination (MMSE) and Word List Recognition (WRL) were the only analyzed variables and MMSE is the one that contributes most to group differentiation
