  1. Crude estimated reduction in counts without controlling for potential confounders. Reduction in counts (95% confidence interval).
  2. *(B-A)- (D-C), with A and B being baseline and 5 months sandfly count in the intervention group and C and D being baseline and 5 months sandfly count in the control group.
  3. † Percent reduction = level of reduction divided by baseline intervention group count. Larger than 100% when the intervention group has decreased while the control group has increased.
