Relationship between PITX genes and clinicopathological parameters in patients with HNSC. The expression of PITX1, PITX2, and PITX3 markedly correlated with (A–C) clinical stage, (D–F) histologic grade, (G–I) T stage, (J–L) N stage, and (M–O) M stage. p ≥ 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001.
