Correlation of carotid-femoral pulse wave velocity and clinical variables by univariable linear regression analysis among the 93 geriatric adults.

| Body mass index (kg/m2) | 0.294 | 0.004∗ |
| Systolic blood pressure (mmHg) | 0.340 | 0.001∗ |
| Diastolic blood pressure (mmHg) | 0.218 | 0.036∗ |
| Pulse pressure (mmHg) | 0.247 | 0.017∗ |

| Log-iPTH (pg/mL) | 0.204 | 0.050 |
| Log-OPN (pg/mL) | 0.351 | 0.001∗ |
∗ P < 0.05 is considered statistically significant in the univariable linear analyses.
Data of fasting glucose, CRP, iPTH, and OPN levels showed skewed distribution and therefore were log-transformed before analysis.
BUN, blood urea nitrogen; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; GFR, glomerular filtration rate; CRP, C-reactive protein; Ca × P product, calcium-phosphorus product; iPTH, intact parathyroid hormone; OPN, osteopontin.
