The relationships between sRAGE and VEGF, TNF-α, IL-6, and CRP in the follicular fluid from the PCOS group. Follicular fluid sRAGE, VEGF, TNF-α, IL-6, and CRP concentrations in follicular fluid were measured with ELISA. sRAGE was significantly, inversely correlated with VEGF (r = −0.378, P = 0.018) (a), TNF-α (r = −0.450, P = 0.004) (b), IL-6 (r = −0.455, P = 0.004) (c), and CRP (r = −0.375, P = 0.019) (d). sRAGE soluble isoform of the receptor for advanced glycation endproducts, VEGF vascular endothelial growth factor, TNF-α tumor necrosis factor α, IL-6 interleukelin-6, CRP C-reactive protein
