1Original category "Nowhere to hang" was expanded to include all aspects of "Unable to hang" reported when the enumerator specified "Other" in the first survey.
2Original category "Normal user absent" was combined with "kept for company", which was often reported when the enumerator specified "Other" in the first survey.
3New category created and kept for subsequent surveys based on the answers frequently given when specifying "Other" in the first survey.
4New category created based on the answers frequently given when specifying "Other" in the first survey but not included as a separate category for subsequent surveys.
5Not included as a separate category for subsequent surveys.
6 For the first survey, "Other" excludes the answers combined into new categories.
The relative proportions of answers given for the main reason why a particular net was not used or why a particular person did not use a net the previous night are provided below. Proportions (unweighted) are given by study arm for each evaluation.
