Heat map of top 50 DEGs in ONFH. a Heat map of top 50 DEGs in GSE123568. b Heat map of top 50 DEGs in GSE74089 (tissue samples are presented as columns; individual genes are presented as rows. Red represents upregulated genes; green indicates downregulated genes in patients with ONFH. The patients in the top rows in pink indicate the control columns; the patients in the top rows in blue indicate columns were patients with NFH. DEGs, differentially expressed genes; NFH, necrosis of the femoral head)
