Figure 1

The 1139 concepts from SNOMED CT’s Bleeding subhierarchy (about 1% of the large Clinical finding hierarchy24), drawn as white boxes organized into levels according to their distance from the root. Only IS-A relationships are shown as lines (colored according to the level of the child concept). The extreme connectedness of SNOMED CT’s concept hierarchy is reflected in the dense mass of lines. Some lines span more than five levels of the hierarchy.
