ALB and chronic kidney disease: For example, red blood cell (RBC) median SSC under 18 h LPS condition (RET_LPS_18 h_RBC_Med_SSC) showed strong positive associations with serum albumin (n = 2,494, t = 11.75, Padj = 3.89 × 10−28) and eGFR (n = 2,569, t = 3.26, Padj = 6.66 × 10−3), which corresponds with its negative association with CKD status.
