Comparison of MMP-2 and MMP-9 concentrations among the study groups.
| Variable | Healthy controls N = 62 |
Non metastatic group N = 62 |
Metastatic group N = 62 |
P-value | Post hoc test |
|---|---|---|---|---|---|

| Mean ± SD | 1.75 ± 1.35 | 3.61 ± 0.79 | 3.60 ± 0.71 | <0.001 | P1 ≤ 0.001 |
| Median | 1.750 | 3.61 | 3.61 | P2 ≤ 0.001 | |
| Min–max | 1.08–2.69 | 1.93–4.95 | 1.99–5.39 | P3 = 0.91 | |

Concentration was expressed in ng/ml. P1 = comparison between healthy controls & non-metastatic groups. P2 = comparison between healthy controls & metastatic groups. P3 = comparison between non-metastatic & metastatic group.
