Table 1 Generalized estimating equations (GEE) analysis of the effect of larviciding on the density of immature mosquitoes, showing the probabilty of the factors

From: Efficacy and persistence of long-lasting microbial larvicides against malaria vectors in western Kenya highlands

  1. This analysis compared larviciding against control. Data from the two larvicides were pooled
  2. aIntervention stage was classified as pre-intervention versus post-intervention
  3. bIntervention was classified as larviciding intervention versus no-larviciding control
