Number of concurrent intestinal parasitic infections, stratified by region among 385 schoolchildren in Burkina Faso. Box plot: boxes illustrate the 25^th and 75^th percentiles (ptile), while the whiskers indicate the adjacent lower and upper values (values which are within 25^th ptile – 1.5 * (75^th – 25^th ptile) and 75^th ptile + 1.5 * (75^th – 25^th ptile), respectively) and values outside these bounds are plotted individually. The median is shown by the line within the boxes
