Correction factors (CF), the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) regression correction (BRC), and restricted cubic splines (RCS) were used to adjust the influence of inflammation on ferritin using alpha-1-acid glycoprotein (AGP) and/or C-reactive protein (CRP). This evidence concerns the gene ATP5MK and anemia (phenotype).
