ATLAS-A: ECG metadata controls

Abstract

This archive contains version 1.0.0 of ATLAS-A: ECG metadata controls, the reproducibility package for a study evaluating whether demographic and anthropometric metadata improve multi-label 12-lead ECG classification beyond ECG-only models. The archive includes analysis code, locked analysis plans, audit records, deterministic verification tests, aggregate numerical results, and sanitized run-level metrics for PTB-XL v1.0.3 and a patient-disjoint CODE-15% inter-dataset replication with retraining. The CODE-15% analysis is not presented as strict external validation of a fixed PTB-XL model because only three target conduction disorders could be harmonized across datasets. Raw ECG recordings, patient-level indices, model checkpoints, prediction arrays, execution logs, and the manuscript are intentionally excluded. The underlying datasets must be obtained from their official repositories. Complete environment, data-preparation, execution, and verification instructions are provided in the accompanying documentation.
