| . | HER2+ . | HER2− . | Total . |
|---|---|---|---|
| Ang-2+ | 15 (R = 0.38182, P < 0.005) | 14 (R = −0.38182, P < 0.005) | 29 |
| Ang-2− | 1 (R = −0.38182, P < 0.005) | 36 (R = 0.38182, P < 0.005) | 37 |
| Total | 16 | 50 | 66 |
| . | HER2+ . | HER2− . | Total . |

NOTE: The nonparametric Spearman's rank correlation was used to analyze for significance of the relationship between HER2 expression and Ang-2 expression (P < 0.005).
