Figure 1
Two-way hierarchical clustering analysis.
Each cell in the 2-dimensional graph indicates the measure of a single mediator in 1 sample, with standardized levels indicated by color according to the scale on the top. Sample clustering resulting from the algorithm described is shown at the right side of the graph, with an indication of the group to which each individual sample belongs. Mediator clustering is depicted on the top of the graph, and detailed at the bottom.
