Wouter van Amsterdam @vanamsterdam.bsky.social · 04/09/2025Pre-print alert: Many ECG-AI models have been developed to predict a wide range of cardiovascular outcomes. But, underrepresentation of women in cardiovascular studies raises the question: Are ECG-AI models equally predictive for women and men with sex-imbalanced training data? 120

Wouter van Amsterdam @vanamsterdam.bsky.social · 24/04/2025Which is stronger evidence for robustness? When evaluating predictive performance of one model in several different environments (e.g. regions / hospitals): A. stable discrimination (AUC) and calibration in all environments B. stable discrimination, varying calibration vote with 👍=A; ❤️=B 311

Wouter van Amsterdam @vanamsterdam.bsky.social · 22/12/2024Digital twins are useful insofar as they reflect causal mechanisms Don't think a generative model ('digital twin') can inform treatment decisions just because it procudes different outputs when you give it different inputs. Doesn't matter if it's 'AI' or not. 160
