The correlation coefficients between ERBB3 methylation and the abundance of immunoinhibitors in cervical cancer are arranged as follows: TIGIT r = 0.656 (p < 0.01), CTLA4 r = 0.642 (p < 0.01), CD96 r = 0.605 (p < 0.01), BTLA r = 0.599 (p < 0.01), HAVCR2 r = 0.57 (p < 0.01), CD244 r = 0.558 (p < 0.01), PDCD1 r = 0.557 (p < 0.01), PDCD1LG2 r = 0.548 (p < 0.01), LAG3 r = 0.519 (< 0.01). Here, ERBB3 is linked to cervical cancer.
