Summary

This study checks if a Withings smart scale can accurately spot signs of high blood pressure by looking at body measurements like weight and heart rate. Researchers compared the scale's results to a standard blood pressure cuff in 2,500 adults. The goal is to see if the scale works as well as an Apple Watch feature already approved by the FDA.
