The AFibrisk platform, a free digital decision-support tool, integrates 19 validated AF prediction scores to support post-stroke triage. We aimed to assess the concordance of AFibrisk-supported classification decisions with expert electrophysiologist consensus and compare performance across evaluator groups with different levels of clinical experience.<h4>Materials and methods</h4>A prospective, cross-sectional concordance study was conducted using 29 standardized clinical vignettes.
