Box plots of iron absorption after uncomplicated malaria. Box plots of fractional iron absorption at three time points during iron supplementation measured in Malawian toddlers assigned to group A (n = 24) and group B (n = 24). Each boxplot represents the medians, 25th and 75th percentiles, lower and upper limits, and dots represent outliers. Additionally, the geometric mean was added as dashed line. Toddlers in group A started the 8-week iron supplementation immediately after malarial treatment and the iron absorption was quantified at week 0, 2 and 8. Toddlers in group B started the 8-week iron supplementation with a 2-week delay and iron absorption was measured at week 2, 4 and 10. Abbreviations: Fe, iron. a,b,c,dWithin and between group comparison: different letters indicate statistical significance (P < 0.05), i.e. if two mean/median values within one parameter carry the same superscript letter, they are not significantly different, i.e. P > 0.05.
