Posterior AD-Type Pathology: Cognitive Subtypes Emerging from a Cluster Analysis
Figure 1
The dendrogram generated by the cluster analysis. Each patient () begins as single clusters and step-by-step the most similar clusters are progressively joined together resulting at the end of the process (in the right-most part of the figure) in a single cluster grouping all the patients. The distance along the -axis represents a measure of similarity between the patients; the vertical red line represents the linkage chosen to select the clusters.
