From: Improving the classification of cardinality phenotypes using collections
Illustration of grouping classes; the green class is an example of a quality-based grouping class decreased cardinality. This class will be inferred to be the superclass of every abnormality of a decreased cardinality of any collection of cells, including decreased cardinality of B cells, decreased cardinality of T cells, decreased cardinality of lymphocytes, etc. the blue classes are examples of grouping based on the entities collection of T cell, collection of B cell, and collection of lymphocytes. For instance, the class abnormality of collection of T cell will be inferred to be the superclass of any abnormality of collection of T cells, including decreased cardinality of T cells, and absent T cells
