The association between FGF1 expression and ccRCC clinical parameters. a Relative FGF1 expression in ccRCC versus normal renal tissues. And the association between FGF1 expression and ccRCC b patients age, c gender, d race, e tumor grade, f lymph node metastasis and g tumor stage. (*p < 0.05, **p < 0.01, ***p < 0.001. The first layer * which is right above the error bar representing comparison to normal group, and the above layers * which were above a secondary line represent the comparison between corresponding groups that were covered by the line). h The hydrophilcity/hydrophobicity analysis of FGF1 protein. i FGF1 centered PPI network representing the genes that were mostly related to FGF1
