Researchers have developed PatTree, a novel graph-based approach for automatically structuring multimodal clinical data into a unified knowledge graph. This method aims to overcome the challenges of data heterogeneity, missing values, and inconsistent formats in real-world clinical data, which often hinder AI applications in medical classification. By preserving semantic relationships across different data sources and modalities without requiring pre-standardization, PatTree facilitates early-stage data integration and enables machine-interpretable data access. Experiments on a subset of the ADNI-1 cohort demonstrated that PatTree achieved state-of-the-art performance in classifying Alzheimer's disease, mild cognitive impairment, and cognitively normal individuals, reaching a balanced accuracy of 98.5%.
