Adsorption is one of the most cost-effectiveness methods to effectively remove pollutants particularly in the low concentration region.
It is therefore straightforward that level one is located in the most cost-effectiveness groups CE_A and CE_B since no additional costs need to be made.
For the BC intervention there was minimal relapse up to the 12-months follow-up and consequently emerged as the most cost-effectiveness intervention on the longer term.
On the whole, the comparison of ICERs (cost per QALY) made the low-dose ITI protocol the most cost-effectiveness approach in a lifetime perspective, followed by the Malmö and then by the Bonn protocol.
In the African sub-region, the most cost effective interventions (average cost effectiveness ratio <$Int200 per DALY averted) were those that targeted individuals at >25% absolute risk of having a cardiovascular event in the next 10 years, either on their own or in combination with an efficient set of secondary prevention measures.
This decision uncertainty surrounding the most cost effective option was not found for place of birth in multiparous low risk women, on whom planned home birth had a 100% probability of being the most cost effective option across all cost effectiveness thresholds between £0 and £100 000 (table 3).
Sensitivity analysis did not show changes for the most cost-effective therapy when the effectiveness probabilities or treatment costs were modified.
To treat populations of this scale, the difference in cost-effectiveness between the most cost-effective treatment option and the least can be as much as 1,400 fold (Disease Control Priorities in Developing Countries Project) [ 25].
Our economic analysis revealed that treating all CHC patients without testing for fibrosis stage was the most cost-effective strategy given a cost-effectiveness threshold of £20,000.
For a given site the different possible retrofit options are ranked in terms of cost-effectiveness and the most appropriate options are highlighted using graphical methods to suggest the most cost-effective combinations of retrofits.
The patient groups were not defined using (randomized) intervention groups, which is the case in most cost-effectiveness analyses, but with the DSQ, which complicates the interpretation of the ICER statistic.
