Label Efficient Transfer Learning Enabling Demographically Robust Cardiovascular Risk Stratification From Electrocardiography Across Geographically Distinct Populations

This deposit provides the reproducibility code, precomputed 38-dimensional ECG feature arrays, evaluation metrics, figure source data, and table values used to assess label-efficient cross-population transfer and demographically robust cardiovascular risk stratification across PTB-XL, Chapman–Ningbo, and MIT-BIH.
