The correlation coefficients between ERBB3 methylation and the abundance of immunostimulators in cervical cancer are arranged as follows: ICOS r = 0.702 (p < 0.01), CD48 r = 0.659 (p < 0.01), IL2RA r = 0.648 (p < 0.01), CD27 r = 0.626 (p < 0.01), CD28 r = 0.607 (p < 0.01), CD86 r = 0.604 (p < 0.01), KLRK1 r = 0.591 (p < 0.01), TNFRSF8 r = 0.585 (p < 0.01), TNFSF13B r = 0.576 (p < 0.01), LTA r = 0.571 (p < 0.01). Here, ICOS is linked to cervical cancer.
