A digital blood pressure gauge is under fire for its inaccuracy,
so the medical association has selected a group of 15 patients.
They were asked to have their (systolic) blood pressure taken first
by an accredited physician (with accurate readings of systolic
pressure), and then to go home and use the digital blood pressure
gauge themselves. The data for the 15 patients tested:
