Frequency (%) of iron deficiency (<i>A</i>), iron deficiency anemia (<i>B)</i> and vitamin A deficiency (<i>C</i>) stratified by inflammation status using combined plasma values of CRP and AGP according to ENFAC study groups.

<p>Reference, CRP ≤ 5mg/L and AGP ≤ 1g/L, <i>n</i> = 302 (<i>A</i> and <i>B</i>) or 296 (<i>C</i>) in CG, and <i>n</i> = 275 (<i>A</i> and <i>B</i>) or 274 (<i>C</i>) in IG; Chronic, CRP ≤ 5mg/L and AGP> 1g/L, <i>n</i> = 83 (<i>A</i> and <i>B</i>) or 84 (<i>C</i>) in CG, and <i>n</i> = 59 (<i>A</i>, <i>B</i> or <i>C</i>) in IG; Acute, CRP >5 and AGP> 1g/L mg/L, <i>n</i> = 68 (<i>A</i> and <i>B</i>) or 65 (<i>C)</i> in CG, and <i>n</i> = 30 (<i>A</i> and <i>B</i>) or 27 (<i>C</i>) in IG. Totals differ from the total number of study children due to missing values for biochemical indicators. The symbol * indicates significant differences for the IG compared with CG (Pearson χ² test).
