Hazard ratio for patienter med EGFR- positive tumorer var 0, 68 (konfidensinterval 0, 49- 0, 94) og 0, 93 (konfidensinterval (0, 63- 1, 36) for patienter med EGFR- negative tumorer (defineret ved IHC under anvendelse af EGFR pharmDx kit og definerende EGFR- negativ som farvning af mindre end 10% af tumorcellerne).
In the 45% of patients with known EGFR-expression status, the hazard ratio was 0.68 (CI 0.49-0.94) for patients with EGFR-positive tumours and 0.93 (CI 0.63-1.36) for patients with EGFR-negative tumours (defined by IHC using EGFR pharmDx kit and defining EGFR-negative as less than 10% tumour cells staining).
