The passage highlights show what phenotypic phrases are identified by each tool. The table demonstrates the HPO terms assigned by each tool to the passage along with their associated phrase. RAG-HPO identifies more phenotypes and assigns more phrases than Doc2HPO or ClinPhen, but fewer than FastHPOCR. However, the terms assigned by RAG-HPO are more precise and relevant than those assigned by FastHPOCR. The passage was adapted from Mughal et al., Cureus 2021. [29]
