Schematic of the cost-effective scale-up pathway. Schematic of the cost-effective scale-up pathway. For each transmission strata, the cost-effective scale-up of interventions was estimated, starting with no intervention coverage then scaling up coverage based on the most favourable incremental cost-effectiveness ratio. Scale-up ceased when all interventions were at full coverage or elimination had occurred. Peter Winskill et al. BMJ Glob Health 2017;2:e000090 Published by the BMJ Publishing Group Limited.
