Fig 4. Correlation of CK2 gene expression to overall patient survival in head and neck cancer.

Patients were stratified into above-median (red line) and below-median (blue line) expression of CK2. (A) High levels of CK2α’ transcript correlated with lower survival (HR = 1.53, 95% CI [1.166, 2.009]; p = 0.002). (B) High levels of CK2β transcript correlated with lower survival (HR = 1.411, 95% CI [1.080, 1.843]; p = 0.0112).
