aBoussoukro and Ouattafouékro are two hamlets situated 1 km apart from each other. For randomisation these two hamlets were considered as one unit
bAmani Kouadiokro, a hamlet at the border of the sub-prefecture, was initially attributed to the control group during randomisation, however, an NGO intervening at the adjacent sub-prefecture erroneously visited the hamlet and carried out a CLTS intervention. Thus, this community was attributed to the intervention group for analysis of parasitological data
cTwo evaluations took place. The first evaluation was implemented on 26–27 November 2011, the second took place on 19–25 March 2012. Kouadio Kouamékro and Amani Kouadiokro were certified ODF following the first evaluation, whereas Katchénou and Yobouékro were certified ODF following the second evaluation
