Description
Topic Overview
Fitness trackers can detect COVID-19 with 80% accuracy and atrial fibrillation with 95% specificity. But what do these numbers actually mean for you?
Key Points to Cover
- COVID-19 detection: 80% AUC, 87.5% accuracy - sounds good but what does it mean?
- Atrial fibrillation: 94% sensitivity, 95% specificity
- Why lab studies dont always translate to real life
- Diverse populations underrepresented in validation studies
