  1. aAssignment at baseline
  2. bAdjusted for age
  3. cAdjusted for age and CRP concentration
  4. dInflammation is defined as CRP >5 mg/l and/or AGP >1 g/l
  5. Odds ratios were assessed in 12- to 36-month-old Ivorian children at 6 and 9 months. The estimations are based on a 2 × 2 factorial analysis using a logistic regression model taking into account random effects
