In these adjusted analyses, megalin (β = 1.92 × 103, FDR < 0.001), lysine (β = 8.81 × 104, FDR = 0.0047), and albumin (β = 844, FDR < 0.001) remained significantly higher in CKD, whereas EGF (β = −1.1 × 106, FDR < 0.001), and the EGF/MCP-1 ratio (β = −0.90, FDR < 0.001) remained significantly lower. Here, ALB is linked to chronic kidney disease.
