Disparity in attack rate among age groups: p-value (base-case)

Attack rate by age group	preschool	school	adult	senior
preschool $(\overline{\mathit{AR}}=44\mathrm{\%})$	–	0.0001***	0.0001***	0.0001***
school $(\overline{\mathit{AR}}=70\mathrm{\%})$	–	–	0.0001***	0.0001***
adult $(\overline{\mathit{AR}}=34\mathrm{\%})$	–	–	–	0.0001***
senior $(\overline{\mathit{AR}}=22\mathrm{\%})$	–	–	–	–

$\overline{\mathit{AR}}$ is the average attack rate computed from 30 simulation replicates
