Concerning distinguishing normal tissue and tumor, the predictive ability of STAT1 has a high accuracy (AUC = 0.957, CI = 0.942–0.973), the predictive ability of MZF1, GPX8, and TBP has a certain accuracy (AUC = 0.792, CI = 0.749–0.834; AUC = 0.809, CI = 0.774–0.845; AUC = 0.703, CI = 0.660–0.745), and the predictive ability of SRF has a lower accuracy (AUC = 0.614, CI = 0.558–0.669) (Figure 6C). The gene discussed is GPX8; the disease is neoplasm.
