Less than 10 % of the terms of the external ontologies are used by the logical definitions of the MPO terms. "Fraction of terms referenced in logical definitions" denotes the percentage of terms in the ontology that are members of the induced ancestral graph and are used by the logical definitions of the MPO terms.
