^a Weighted analysis of 2004 Yoto data takes into account the variability of the enumeration area cluster size during the first 3 survey days (Crude number of households = 543); ^b These estimates are based on the household coverage survey that visited all selected households independent of the presence of children; ^c 2004 data reported by caretaker, 2005 data based on direct observation at home visit (n households = 1791, n children = 2751 of 2813); ^d 2004 data not collected, 2005 data based on direct observation; ^e Based on reported number of campaign nets received by households with >=2 children targeted by the campaign, i.e. >=18mo of age at time of 2005 survey (Yoto n = 128, Ogou n = 121, Tone n = 162); ^f "ITN use" was defined as a positive answer at the time of the morbidity survey in a central location to the question 'did this person sleep under an ITN last night?'; ^g "ITN hanging" was defined as a positive answer at during the home visit from the GPS team to the question whether a net was hanging. At this time, where people allowed, staff visually confirmed that an ITN was tied over a sleeping space, even if the net was folded above the bed. ** Differences between districts P < 0.001; *** Differences between districts = p < 0.0001.
