Key lab findings included albumin <35 g/l, anemia with hemoglobin <10 g/l, elevated β2-MG >5.5 mg/l, reduced estimated glomerular filtration rate (eGFR) <60 ml/min/1,73 m2, and elevated serum phosphate (PO43-) >1.45 mmol/l, all tied to a higher SI risk (Table 4, Figure 1B). Here, ALB is linked to anemia (phenotype).
