The 2 parameters that remained in the model were tumour grade (OR 0.14, 95% CI: 0.07-0.31; p < 0.001) and endothelial-FAK expression (OR 0.03, 95% CI: 0.01-0.25; p = 0.001, Table 5), suggesting that low endothelial-FAK expression is independently associated with the luminal A sub-type, even after taking tumour grade into account. This evidence concerns the gene PTK2 and neoplasm.
