Fig. 4From: Identification of blood-based key biomarker and immune infiltration in Immunoglobulin A nephropathy by comprehensive bioinformatics analysis and a cohort validationCorrelation analysis of DEGs and corresponding clinical characteristics of estimated glomerular filtration rate (eGFR) and proteinuria to identify the protective genes. Protective gene was defined as eGFR positive correlated and proteinuria negative correlated in downregulated genes whereas the opposite trend in upregulated genes. A A total of 6 genes were found, including 3 upregulated (left) and 3 downregulated protective genes (right). B Correlation maps of above-identified 6 genes were shown, including ORMDL2, NRP1, COL4A1, ST13, HSPA8 and PKP4Back to article page
