Dendrogram of the dataset. The label under the dendrogram indicates the information of the data, i.e., ossicle to which the fixed ligaments were attached, and the color indicates degree of the fixation, as follows: normal in green, 10-times stiffened in yellow, 100-times stiffened in orange, and 1000-times stiffened in red. The blue dashed line indicates the threshold used for the classification into four groups. Features of classified data are indicated at the bifurcation. The features were determined based on the details of fixation degree and fixation location of the classified data, and significant difference of the ossicular compliances among the groups.
