Linear regression analysis of Ki-67 positive nuclei (% of tumor tissue) in correlation to the Hercep-Score of the EpCAM staining for primary tumor tissue and lymph node metastasis. The slope of line for the primary tumor samples (n=163) was 24.64 [95% confidence interval (CI), 16.4 to 32.89] and the correlation coefficient (r2) 0.9881. For lymph node samples (n=88) the slope of the line was 3.466 [95% CI, 1.299 to 5.633] and the r2 0.9595. The dots/squares illustrate the mean value and the error bars the standard error of the mean (SEM). The slope of the lines deviated both significantly from zero (primary tumor: p=0.006; lymph node metastasis: p=0.02).
