Incidence rates (first episodes) by Giardia infection status at baseline, and by intervention group.

Values between brackets indicate the number of episodes/child-years observation time. Incidence rate ratios [95% CI] are crude estimates based on the analysis first or only events. An incidence rate ratio of Far right column: p-values for differences between incidence rate ratios in children with and without multi-nutrients (based on Cox proportional hazards model that included interaction term between multi-nutrients and Giardia).Numbers in intervention groups: without multi-nutrients: n = 306 (96 Giardia positive, 185 negative, 25 missing); with multinutrients: n = 306 (96 Giardia positive, 181 negative, 29 missing).a19,12 and 13 cases of reported diarrhea, diarrhea with ≥3 loose stools/24 h and fever without localizing signs occured in children for whom Giardia status was unknown.
