Figure 3: Unadjusted Kaplan-Meier Curves by PDK-1 staining intensity. Patients with high levels of PDK-1 staining (above median: solid line) in peripheral tumor show a trend toward worse overall survival (A) and recurrence free survival (C) that does not quite reach statistical significance. The PDK-1 staining intensity in central tumor shows no association with overall survival (B) or recurrence free survival (D).
