  1. Crude Odds Ratios (OR) and adjusted OR of the effect of each variable on the likelihood of sleeping under a bed net the night before of the survey (n = 3823).
  2. 1Only children under 5 from households which owned at least one net were included.
  3. 2For the purpose of this analysis, missing data in any of the variables analysed were excluded.
  4. 3Adjusted Odds Ratios and p values using a multiple regression model adjusting for all variables presented in the model.
  5. 4P values obtained through Wald Tests.
  6. 5Adjusted Odds Ratios using a model adjusting for all the variables of the model and the interaction of this variable with "year". The p-value for the test of interaction of "year" with "owning at least one ITN" was 0.02
  7. 6Knowledge questions asked to the household interviewee.
