Worm dimensions show population of heavy worms was reduced at follow-up. Each worm’s length and weight was measured on the day it was collected. There was a longer gap in time between worms collected in Ranje (the pilot study village), as worms there were collected during the pilot, and then only after the follow-up data collection had finished in the four main study villages. a The length of each worm is plotted against the width of that worm, to show the concentration of small worms at all time-points and the small number of heavy, long worms still present at the post-treatment time-points. b The weights of these same worms are plotted as interleaved histograms, to show that the distribution of worms shifts to the left post-treatment
