Incidence rate ratios (IRR) estimated from a mixed-effects Poisson regression model evaluating effect of treatment (deltamethrin vs control and bendiocarb vs control) on each adult entomologic metric.

The model included city block (where individual observations are nested) and cluster (grouping of 3 treatments) as random intercepts. IRRs were calculated by considering control blocks as comparison. Numbers in bold show statistically significant (P<0.05) difference between the treatment and the control.
