NAB2 and metastatic neoplasm: Whereas the high EGR1/low NAB2 cluster presented with significantly fewer metastatic tumors (32 metastatic/81 total tumors; hypergeometric p = 0.005), the high EGR1/high NAB2 cluster was associated with a significant increase in metastatic tumors (20 metastatic/31 total tumors; hypergeometric p = 0.043; Figure 5D).
