  1. Bold values indicate non inferiority criterion
  2. Non-inferiority of Panda® Net 2.0 and Yahe® LN combined feeding inhibition and 24 h mortality with PermaNet® 2.0 as the reference. The candidate net is deemed non-inferior if (i) the upper 95% CI estimate of the odds ratio (OR) describing the difference in mosquito blood feeding between the candidate net and PermaNet 2.0 is greater than 1.43; (ii) the lower 95% CI estimate of the OR describing the difference in mosquito mortality between the candidate net and PermaNet 2.0 is greater than 0.7
  3. Outcome values (mean) in the same column sharing the same letter superscript do not differ significantly at a 5% level (GLM, p > 0.05)
