Figure 3: Box-and-whisker plot showing the relationship between median and range of haemoglobin levels (g/dL) at baseline () and at 5 months () and 8 months () after baseline treatment for the single-dose and double-dose Praziquantel treatments. The thick line within each box stands for the median haemoglobin value. The lower and upper edges of each box represent the 25th and 75th percentiles, respectively. The lower and upper whiskers represent the lower and upper values (range), respectively, excluding outliers.
