Significantly Reduced Blood Pressure Measurement Variability for Both Normotensive and Hypertensive Subjects: Effect of Polynomial Curve Fitting of Oscillometric Pulses

Table 2

Blood pressures measured from different techniques for both normotensive and hypertensive groups and the BP differences between the two automatic oscillometric technique and manual auscultatory techniques (calculated from the automatic-manual auscultatory). The data are presented with means and SDs.
