Fig. 3From: Effects of definitive chemoradiation on circulating immunologic angiogenic cytokines in head and neck cancer patientsCorrelations between tumor, treatment parameters and circulating angiogenic cytokines, as evaluated by non-parametric Wilcoxon signed rank tests. Changes in Ang2 (Delta-Ang2) and in PlGF (Delta-PlGF) values correlate with disease present in lymph nodes (p = 0.02, and 0.008, respectively, top panel). Delta-PLGF values also correlate with addition of concurrent chemotherapy (p = 0.02, bottom panel)Back to article page
