Table 2.
Multi-linear regression models between OEF, diagnosis and VRS in the whole group (N=65). In all models, OEF was the dependent variable, the independent variables are listed below.
| Independent variables | β±SE | P-value | |
|---|---|---|---|
| Model 1 | Diagnosis | −2.70±1.15 | 0.02 |
| VRS | 1.36±0.55 | 0.02 | |
| Age | 0.25±0.10 | 0.02 | |
| Sex | 0.59±1.48 | 0.69 | |
| Model 2 | Diagnosis | −2.99±1.13 | 0.01 |
| VRS | 1.19±0.54 | 0.03 | |
| Diagnosis×VRS | 1.69±0.78 | 0.04 | |
| Age | 0.22±0.10 | 0.03 | |
| Sex | −0.03±1.46 | 0.99 |
β: standardized beta coefficient; SE: standardized error; VRS: vascular risk score; OEF: oxygen extraction fraction.
