Sensitivity analyses were performed in which the ferritin threshold to define iron deficiency was raised, the CRP threshold to define inflammation was lowered from 5 mg/L to 1 mg/L, and in which only children with a mean cell volume higher than 73 fL (aged 6–23 months) or higher than 75 fL (aged 24–59 months) were included. This evidence concerns the gene CRP and Iron deficiency anemia.
