Identification of clinical-biological endophenotypes in patients with eosinophilic granulomatosis with polyangiitis using unsupervised machine learning: a real-world study
Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic vasculitis characterized by high clinical heterogeneity. The conventional binary classification based on antineutrophil cytoplasmic antibody (ANCA) status inadequately captures this heterogeneity and provides limited guidance for individualised treatmen...
