Estimated prevalence [% (95% CI)] of depleted iron stores on the basis of internal regression correction adjusting for CRP, AGP, or both in preschool children: Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project. Depleted iron stores were defined as a ferritin concentration <12 μg/L. Internal regression correction reference values were as follows: C-reactive protein = −2.26 ln(mg/L) [QE (df = 10) = 439.9, P < 0.0001]; and α-1-acid glycoprotein = −0.52 ln(g/L)] [QE (df = 10) = 584.6, P < 0.0001]. Bars without a common lowercase letter within a given survey differ, P < 0.05 (adjusted by using Bonferroni correction). AGP, α-1-acid glycoprotein; CRP, C-reactive protein.
