Association of biomarkers with survival.

|
|---|---|---|---|
| HR | Adjusted HRa | HR | |
| pERK (intensity)b | 1.36 | 0.99 | 0.94 |
| pERK (H-value) | 1.45 | 0.74 | 0.88 |
| pERK (percentage) | 1.45 | 0.74 | 0.88 |
| Ki-67 (H-value) | 0.28c | 2.00 | 0.72 |
| Ki-67 (percentage) | 0.63 | 0.56 | 0.39 |
HR = unadjusted hazard ratio for the relevant endpoint with the biomarker evaluated at higher levels to lower levels.
Adjusted hazard ratio modeled with platinum sensitivity and performance status factors.
pERK was dichotomized into cases with 0+ intensity (8 patients) versus cases with 1+ or 2+ intensities (11 patients).
Data suggest an association by permutation test.
