^aSignificant differences in investigated parasite infection prevalence between boys and girls were found for Giardia intestinalis (P = 0.05)
^b Trichomonas intestinalis and multiple parasitic infection prevalence were significantly different between age groups (P < 0.05)
^cSignificant regional differences were found for Hymenolepis nana, any faecal-oral transmitted helminth, Entamoeba histolytica/E. dispar, Entamoeba coli, Trichomonas intestinalis, Entamoeba histolytica/E. dispar or Giardia intestinalis, total intestinal protozoa infection, and multiple intestinal parasitic infection (P < 0.05)
^dPC, Plateau Central; CO, Centre-Ouest region of Burkina Faso
^eThe category of total faecal-oral transmitted helminths includes children infected with hookworm and Hymenolepis nana. There was one child co-infected with hookworm and Hymenolepis nana
^fSeveral children were co-infected with intestinal protozoa. The total of this category therefore does not sum up from the separate figures
^gMultiple intestinal parasitic infection was defined as dichotomous variable, classified as > 1 infection vs ≤ 1 infection
