AGP, α1-acid glycoprotein; SIVIN, Sistema Integrado de Vigilancia de Intervenciones Nutricionales (Integrated Surveillance System for Nutrition Interventions).
Elevated AGP is AGP>1·0 g/l; normal AGP is AGP≤1·0 g/l.
P values indicate a difference in prevalence of serum ferritin by weight status and are based on Rao–Scott χ 2 test.
