Table 4. A summary of arterial volume distensibility as a function of systolic blood pressure (SBP), diastolic blood pressure (DBP) and age.
| Variables | Regression function: distensibility (% per mmHg) = | P-value | R-value | % change of distensibility |
|---|---|---|---|---|
| SBP | ||||
| Normal | −0.00034 × SBP + 0.099 | 0.021* | 0.37 | −30 (from 90 to 150 mmHg) |
| BRVO | −0.00040 × SBP + 0.10 | 0.027* | 0.41 | −38 (from 90 to 150 mmHg) |
| DBP | ||||
| Normal | −0.00042 × DBP + 0.089 | 0.016* | 0.38 | −36 (from 45 to 105 mmHg) |
| BRVO | −0.00062 × DBP + 0.094 | 0.037* | 0.38 | −56 (from 45 to 105 mmHg) |
| Age | ||||
| Normal | −0.00060 × Age + 0.092 | 0.045* | 0.32 | −18 (from 45 to 65 year) |
| BRVO | −0.00088 × Age + 0.090 | 0.008** | 0.47 | −35 (from 45 to 65 year) |
