| Clinical/pathologic parameters | Correlation with blood flow | Correlation with MRFDG | ||
|---|---|---|---|---|
| Correlation measure | P | Correlation measure | P | |
| Age | r = −0.26 | 0.11 | r = −0.40 | 0.01 |
| Tumor size | r = 0.11 | 0.52 | r = −0.05 | 0.76 |
| Clinically positive nodes | t = −0.24 | 0.81 | t = −0.69 | 0.50 |
| Menopausal status | t = 0.13 | 0.90 | t = 1.00 | 0.31 |
| Tumor grade | τb = 0.15 | 0.26 | τb = 0.31 | 0.02 |
| ER expression | τb = −0.27 | 0.04 | τb = −0.14 | 0.28 |
| c-erbB-2 expression | τb = −0.05 | 0.71 | τb = −0.02 | 0.86 |

Correlation measures are r for continuous variables, τb for nominal variables, and t for dichotomous variables.
