<qa>  What was the goal of the project?The specific objective of this project was to demonstrate the CareTakers ability to perform self-calibration to the same performance standard as its predicate device. That device demonstrated efficacy by showing substantial equivalence to the performance of classical sphygmomanometry using a Riva-RocciKorotkoff RRK measurement on the brachial artery, meeting a bias of at least 5 mmHg and a standard deviation of 8 mmHg across 3 paired readings from at least 85 patients, for a total of at least 255 paired readings.
