Estimated IIV VE by Day 30 and fold-rise HAI and NAI titer variables. Estimated VE by a Day 30 HAI titer if assigned vaccine, b fold-rise in HAI titer if assigned vaccine, c Day 30 NAI titer if assigned vaccine, d fold-rise in NAI titer if assigned vaccine. Each solid black line is the estimated VE by the Juraska (2018) method [48]. Dashed and dot-dashed black lines are pointwise and simultaneous 95% confidence intervals, respectively. Each dotted red line is the estimated overall VE. P-values shown are 2-sided p-values for effect modification
