*Values represent mean±SD for continuous variable or N (%) for dichotomized variables. Stunting defined as LAZ<-2; anemia defined as Hb <110 g/L.
†Values represent median (IQR) for continuous variable or N (%) for dichotomized variables. Zinc deficiency defined as plasma zinc concentration <65μg/dL. Plasma zinc data adjusted for inflammation.
