Table 2 The odds ratio [95% confidence interval] of monthly mortality rates of An. marajoara after 24 h post-exposure to alpha-cypermethrin, etofenprox WP, and lambda-cyhalothrin CS on four different surfaces: plastered cement wall (CP1), unplastered cement wall (CP2), painted wooden wall (WP1), and the unpainted wooden wall (WP2)
