∗Statistically significant at 5% level.
Where the row and column meet, is the correlation coefficient and the 𝑃 value for the two variables.
VEGF: vascular endothelial growth factor; sVEGFR-2: soluble vascular endothelial growth factor receptor-2; SCF: stem cell factor; s-kit: soluble c-kit; PGE₂: prostaglandin E₂.
