Fig. 3From: Association of Elevated Protein Kinase CK2 Activity with Aggressive Behavior of Squamous Cell Carcinoma of the Head and Neck Cumulative survival curves based on CK2 levels The median value of 4.8 for cytosolic CK2 activity in primary SCCHN tumors was used to divide patients into High-CK2 and Low-CK2 activity groups. The cumulative survival curves for the two groups were calculated by the Kaplan-Meier method. Chi-square analysis reveals a statistical significance between the two groups of p < 0.023.Back to article page
