GNG2 and cancer: Logistic regression analysis revealed that lower GNG2 expression was significantly correlated with higher stage of cancer (OR = 0.616 for stage II vs. I, p < 0.01), higher tumor proliferation (OR = 0.584 for > 2 cm vs. ≤ 2 cm; p < 0.001), higher tumor status (OR = 0.091; p < 0.001), and higher age (OR = 0.681; p < 0.001; Table S6).
