Table 4: The predictive power of EGFR, Her2/neu, phospho-EGFR, phospho-Her2/neu in breast cancer survival assessment on this study cohort (N=235). Six parameters for antibody measurements were included in the analysis of phospho-EGFR, phospho-Her2/neu, and EGFR. P value represents the statistical significance of the improvement over the control analysis
