Results are presented in terms of change in mortality of mosquitoes for each year since a mass bednet distribution took place in-country. Odds ratios are adjusted for locality and temperature and humidity where indicated. The results are shown for each country, as well as all countries combined (with country included as a covariate). Cluster was included as a random effect in all models
