TNFRSF10B and neoplasm: However, when assessing staining intensity for TRAIL-R2, this receptor appeared to have a lower staining in tumor tissue samples compared to matched non-tumor tissue, with the majority of non-tumor samples showing high intensity-staining (high intensity-staining in non-tumor tissue samples = 71% vs. 48% of tumor tissue samples - McNemar-Bowker test: p = 0.021, table S2).
