Moreover, Kaplan‒Meier analysis showed that among those 7 IRGs, high expression of ULBP2, CCL24, NPR3, and ANO6 predicted a poor prognosis in BC patients, while high expression of TSLP, FLT3, and TNFRSF8 was correlated with an optimal prognosis in BC patients (Figure S1). Here, ULBP2 is linked to breast cancer.
