Fig. 3From: Exploring the key genes and pathways of side population cells in human osteosarcoma using gene expression array analysisThe distribution of core genes in the interaction network. The black node means the core gene. The red line means the fitted line, and the blue line means the power law. The correlation between the data points and corresponding points on the line is approximately 0.932. The R-squared value is 0.846, giving a relatively high confidence that the underlying model is indeed linearBack to article page
