Ear nerve stimulation shows no significant overall blood-pressure benefit versus sham in small trial

In a 63-person randomized trial described in Queen Mary University of London's account on ScienceDaily, at-home ear nerve stimulation showed no statistically significant difference in blood-pressure changes compared with a sham device overall. A planned analysis found greater reductions among participants with more severe hypertension, but the university says larger studies must confirm that result before drawing conclusions about effectiveness.
