Figure 6From: Cytogenetic analysis of HER1/EGFR, HER2, HER3 and HER4 in 278 breast cancer patientsUnivariate analysis of HER1–HER4 FISH. Comparison of individually calculated hazard ratios (overall survival, HRind = exp [B HERx × HERx continuous]), based on the hazard ratio in one-tenth intervals showing the rising or declining hazard level as a function of increasing fluorescence in situ hybridisation (FISH) ratio.Back to article page
