Disparity analysis of attack rate among income groups: p-value (base-case)

Income quartiles	Q1	Q2	Q3	Q4
Q1 $(\overline{\mathit{AR}}=32\mathrm{\%})$	–	0.0001***	0.0001***	0.0001***
Q2 $(\overline{\mathit{AR}}=36\mathrm{\%})$	–	–	0.0001***	0.0001***
Q3 $(\overline{\mathit{AR}}=41\mathrm{\%})$	–	–	–	0.0001***
Q4 $(\overline{\mathit{AR}}=46\mathrm{\%})$	–	–	–	–

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

^*p < .05,
