  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.
