CI: confidence interval; C-index: concentration index; ITN: insecticide-treated net.
Notes: Cover The Bed Net Gap was an initiative launched by the Roll Back Malaria Partnership in April 2008.12 Years of the surveys are given in Table 1. A value of 0 suggests no difference in ITN ownership between different wealth quintiles. A C-index larger than 0 suggests that ITN ownership is concentrated among the richer households. Conversely, a negative index indicates that ITN ownership is more concentrated among the poorer households.17,38
