IPIM (Idiopathic Pulmonary Fibrosis Phenotypes Identification Model)

The IPIM (Idiopathic Pulmonary Fibrosis Phenotypes Identification Model) was developed within the Assiut University IPF Research Program (2022–2026) to define and classify biological and clinical phenotypes in idiopathic pulmonary fibrosis (IPF).IPIM distinguishes inflammatory-predominant and fibrotic-predominant phenotypes by integrating clinical, functional, and radiological domains, providing a practical framework for precision-guided management and prognostic differentiation.The model was officially locked and adopted for research use in April 2023 as part of the Assiut University IPF Research Program, representing the first phenotypic classification system validated within a complete longitudinal IPF cohort. © 2025 Faculty of Medicine, Assiut University — Assiut, Egypt.All rights reserved under CC BY-NC-ND 4.0 License.Official disclosure for DOI registration through Zenodo.
