Values are expressed as the mean ± standard error of the mean. The means were obtained by adjusting the minimum squares. All analyses were adjusted for age. Serum ferritin was adjusted for C-reactive protein and alpha-1 acid glycoprotein. n = number of participants in the intervention group. ni = initial number of participants. nf = final number of participants. 1 MNP = Multiple micronutrients powder. 2 FS_FA = Ferrous sulfate and folic acid. 3 Significance of the difference between the effect of the two interventions at the baseline and after intervention—ANOVA. 4 Significance of the effect of groups within interventions (nested)—ANOVA. For serum ferritin, there was an effect of CRP (p < 0.001) and AGA (p = 0.012), which were used in all analyses as covariates.
