Time-tradeoff amounts for 2009 pandemic influenza (A) H1N1 illness and vaccination-related adverse events1.

1Using unweighted data.2To generate confidence intervals around our mean values, we used bootstrap re-sampling of size equal to the sample size (approximately 1300, depending on the health state) with 3000 iterations. From each of the 3000 bootstrap samples generated, we calculate the overall means and means by scenario age to create a sampling distribution around the original mean values.3Kruskal-Wallis test evaluated whether median values differed by scenario age.
