The behavioural mechanism around that is—what we believe happened—because this application prompted them to take their blood pressure measurements on a more regular basis, these patients became more aware of their blood pressure. They took their medications more frequently, and the follow-up was closer.
For those patients, again, hypertension was asymptomatic. With the patients who had none of that engagement with a conventional blood pressure monitor, they often forgot. We suspected that the group hadn't used the blood pressure device very frequently, and obviously hadn't taken their medications on a more regular basis. It is a behavioural intervention in the end.
