Predicted hypertension screening accuracy versus precision accuracy for systolic BP measurements via a PTT-based system as well the PTT-based system and conventional auscultation combined. Hypertension screening accuracy is quantified in terms of the probability of correctly detecting systolic BP >145 mmHg or <135 mmHg via many measurements from the PTT-based system and two consecutive auscultation measurements for the combined system. Precision accuracy is quantified in terms of the standard deviation of individual measurements from the PTT-based system in an AAMI protocol.
