So, according to this, the false positive rate for the Apple Watch in detecting atrial fibrillation is 0.04% (99.6% correct) This means that, on average, Apple Watches will be wrong more than 80% of the time Sound counterintuitive? This is the issue with population screeninghttps://twitter.com/statnews/status/1040273579391242242 …

This false identification rate can be reduced if the proportion of the population at risk increases For example, if 10% of the population have AF, then the watch only gets it wrong a tiny percentage of the time

This is why screening is usually only recommended in very high-risk populations

Even if it is wrong ⅓ of the time that is still a huge number. That’s a lot of people running to a cardiologist getting tested.

Yeh that's why I left it up. Also, I used a high prevalence estimate, using a more conservative estimate it comes out as closer to the 80% again. The fewer people have AF, the worse the Apple Watch is
