From: Stable malaria incidence despite scaling up control strategies in a malaria vaccine-testing site in Mali

Years Transmission season** Number of cases Person-year Incidence rate *IRR (95% CI) p
2009*** High transmission season 276 157 1.7   Ref
2010 Overall 456 324 1.4   
  Low transmission season 32 115 0.3   
  High transmission season 424 208 2 1.15 (0.99–1.35) 0.05
2011 Overall 458 352 1.3   
  Low transmission season 58 149 0.4   
  High transmission season 400 202 1.9 1.12 (0.96–1.31) 0.11
2012 Overall 672 335 2

  1. *IRR = Incidence rate ratio for high transmission season; 95% CI is 95% confidence interval.
  2. **Transmission season; High transmission season was from June-December (rainy season) and low transmission season was from January-May (dry season).
  3. ***2009 high transmission season was used as reference (Ref) in estimating IRR for other years during high transmission season.
