## Overview

This repository is a small set of ECG-AI data-processing scripts. The README says they assume existing five-year atrial-fibrillation risk inferences, but does not describe their outputs or how the scripts call shared functions. The script names indicate Cox/IPCW and UKBB two-year analyses; their implementation and wiring cannot be confirmed because no source excerpts were provided.

Main entry points: [`cox_ipcw.R`](https://github.com/shaankhurshid/ecg_ai/blob/main/cox_ipcw.R) (Cox IPCW processing), [`cox_ukbb_2y.R`](https://github.com/shaankhurshid/ecg_ai/blob/main/cox_ukbb_2y.R) (UKBB 2-year analysis)
