(A) The reduction in final infection size across a range of intervention effectiveness (1.0 is a fully effective intervention), accounting for a range of assortativity. Between-group mixing of 1.0 equates to between-group mixing as likely as within-group mixing. Each line represents the mean reduction (of 200 simulations) resulting from an intervention, and is associated with a β matrix specific to the degree of between-group mixing illustrated; (B) The relative distribution of group sizes at three levels of intervention effectiveness (0.0, 0.2, 1.0).
