Data Supplement from Influence of Biospecimen Variables on Proteomic Biomarkers in Breast Cancer

Supplementary Table 5: The tumor cellularity of each biospecimen as assessed by H&E Supplementary Table 6: Correlation of protein expression by RPPA between different biospecimens (Spearman's correlation). Analysis was conducted in samples with 20% cellularity as well as in all samples separately. Supplementary Table 7: Comparison of protein expression by RPPA between different biospecimens (Student's t-test) Supplementary Table 8: Correlation of biomarker expression by RPPA between CNB, central and peripheral samples based on biospecimen variables Supplementary Table 9: Correlation of biomarker expression by RPPA and tumor cellularity in CNB, central and peripheral samples. Analysis was conducted in samples with 20% cellularity as well as in all samples separately. Supplementary Table 10: Correlation of biomarker expression by RPPA in CNB and FNA with central and peripheral samples based on whether neoadjuvant chemotherapy had been administered.
