Multivariable stepwise linear regression analysis of carotid-femoral pulse wave velocity among 93 geriatric adults.
| Items | Beta | R 2 change | Regression coefficient (95% confidence interval) | P value |
|---|---|---|---|---|
| Log-OPN (pg/mL) | 0.233 | 0.123 | 1.868 (0.444 to 3.291) | 0.011∗ |
| Body mass index (kg/m2) | 0.333 | 0.093 | 0.243 (0.119 to −0.367) | <0.001∗ |
| Creatinine (mg/dL) | 0.195 | 0.074 | 1.517 (0.123 to 2.911) | 0.033∗ |
| Age (years) | 0.250 | 0.047 | 0.130 (0.037 to 0.223) | 0.007∗ |
| Diabetes | 0.195 | 0.035 | 1.090 (0.108 to 2.072) | 0.030∗ |
Data of osteopontin levels showed skewed distribution and therefore were log-transformed before analysis.
∗ P < 0.05 was considered statistically significant in the multivariable stepwise linear regression analysis (adopted factors: diabetes, dyslipidemia, age, waist circumference, body mass index, systolic blood pressure, diastolic blood pressure, pulse pressure, HDL-C, creatinine, GFR, and log-OPN).
HDL-C, high-density lipoprotein cholesterol; GFR, glomerular filtration rate; OPN, osteopontin.
