Estimated cost per incident of physical or emotional abuse averted, including sensitivity analysis to uncertainty around the effect size and the costs of implementation at scale

	Cost of implementation per family (US$)	Estimated cost per incident averted (US$)	Sensitivity to uncertainty around the effect size*
	Cost of implementation per family (US$)	Estimated cost per incident averted (US$)	Lower bound	Upper bound
Trial	504	1837	4688	1152
Sensitivity to different models of implementation at scale
Modelled at scale	266	972	2480	610
Modelled at scale plus 50%†	399	1445	3720	914
Lean model‡	146	489	1249	307

*Bounds are calculated using the lower and upper values of the 95% CI around the effect size.
†This model adds 50% of the calculated budget for the delivery of the programme at scale, allowing for unforeseen variations in context that may increase costs.
‡This model assumes delivery at scale with the modelled cost, but with reduced transportation, and no food or home visits for participants.
