Figure 7. Number of mobile lice (including adult females) before (green) and after (orange) delousing, separated by treatment method. Mean delousing efficacy (%) per Method is also given. Number of sessile lice is not included as these data were judged too unreliable. The middle line of the boxplots is the median, the upper and lower parts of the boxes are the 75- and 25-percentiles, the whiskers the highest/smallest value within the 1.5*the interquartile range, and the dots the values outside the whiskers.
