Comparison of survival between different stages.
| Stage | N | Mean | Std error | Median (D) | Lower 95% | Upper 95% | p |
|---|---|---|---|---|---|---|---|
| I | 8 | 1108.6 | 220.4 | 1,112 | 290 | 1,818 | |
| II | 9 | 741.4 | 354.0 | 336 | 42 | 1,211 | |
| III | 12 | 181.3 | 41.1 | 131¤ | 48 | 279 | 0.0001 |
| IV | 3 | 45 | 12.6 | 55 | 20 | 60 | |
| I+II | 17 | 914.2 | 212.8 | 500 | 290 | 1,211 | |
| III+IV | 15 | 154.1 | 35.7 | 128* | 48 | 160 | 0.0001 |
| Combined | 32 | 558 | 131.6 | 285 | 130 | 495 |
Stages also merged in low (I+II) and high (III+IV) to equal group size. Survival was significantly lower in stage III compared to all other groups. When only comparing low (I+II) and high (III+IV) stage, it was a significantly worsened prognosis in high stage.
