Fig 9. The relative risk reduction (RRR) of outcome (II): Having outbreak with final size c > 100 as a function of the relative reduction in reproduction number (ξ).

The RRR of control scheme (I) RRR⁽¹⁾(ξ) is dashed cyan curve, and the RRR of control scheme (II) RRR⁽²⁾(ξ) is bold orange curve. In each panel, the dispersion parameter k is fixed at 0.2, and the shading region indicates the situation that ξ ≥ 1 − ρ. In each panel label, ‘R’ is the reproduction number, and ‘fixed frac.’ is the fraction of fixed component (ρ).
