  1. HI house improvement, LSM larval source management, RDT rapid diagnostic test
  2. aEffect size estimates are presented as odds ratios based on individual-level generalized linear models with the control arm as the reference category
  3. bSelf-reported fever in the last 48 h or body temperature measured over 37.5 °C
