Anaemia prevalence (%), Hb (mean ± SD) and ferritin concentrations (median, IQR) of the different treatment groups after 6 months of daily consumption of the multi-nutrient fortified dairy-based drink.

	200 mL	400 mL	600 mL	Treatment Effect p-Value
Anaemia prevalence (%)	47.1 a	27.0 a,b	17.6 b	0.03
Hb (g/dL)	11.2 ± 0.9 a,*	11.6 ± 0.9 b,*	11.7 ± 1.0 b,*	0.005
Ferritin (µg/L)	37.0, 19.3	34.7, 35.1	39.5, 28.4	0.84

* Significantly higher compared to baseline concentration (p < 0.05). Chi-square test was used for anaemia prevalence, one-way ANCOVA for Hb and ferritin with corresponding baseline concentrations taken along as covariate. In contrast to baseline concentrations, Hb at endline was normally distributed, and although this was not the case for ferritin ANCOVA was considered robust enough to apply for ferritin as well. Within treatment groups, concentrations before and after the intervention were compared using either paired t-test or Wilcoxon signed-rank test. Different letters in superscript (a and b) indicate differences between treatment groups.
