Table 2 The association between deltamethrin and permethrin mortality on malaria prevalence
Insecticide | Effect of | Malaria prevalence in children aged 6 months to 10 years, % (n/N) | Odds ratio (95% CI) | Adjusted odds ratioa (95% CI) | |
|---|---|---|---|---|---|
Deltamethrin | Dichotomized resistance | Lower resistance (mosquito mortality >55.2%) | 50.2% (413/822) | 1 | 1 |
Higher resistance (mosquito mortality <55.2%) | 52.9% (423/799) | 1.11 (0.65, 1.90), p = 0.698 | 1.04 (0.60, 1.81), p = 0.877 | ||
Linear increase in mosquito mortality | 10% increase | – | 1.00 (0.85, 1.17), p = 0.999 | 1.03 (0.88, 1.21), p 0.734 | |
Permethrin | Dichotomized resistance | Lower resistance (mosquito mortality >18.2%) | 53.5% (417/780) | 1 | 1 |
Higher resistance (mosquito mortality <18.2%) | 50.8% (387/762) | 0.88 (0.50, 1.53), p = 0.640 | 0.86 (0.49, 1.51), p = 0.600 | ||
