Table 3 Results of a Poisson regression model of the number of An. gambiae s.l. inside ITNs in Bungoma County including the model estimates, risk ratios and P-values

From: The efficacy of long-lasting nets with declining physical integrity may be compromised in areas with high levels of pyrethroid resistance

  1. The 95% CI for the estimate and risk ratios are given in parentheses. Significant P-values are given in boldface.
  2. *Nets of unknown age were categorized as older than three years. Additional models were run with nets of unknown aged categorized as less than or equal to three years and the results did not change substantially.
