The following criteria were used to evaluate interventions:

1. Cost effectiveness: Cost per QALY gained, including the healthcare costs avoided and quality of life gains associated with the long-term health impact.
2. Reach: The proportion of the total population benefitting for the intervention.
3. Inequality score: The ratio of the proportion of the most disadvantaged 20% of the population eligible for the intervention to the proportion of the whole population eligible for the intervention.
4. Affordability: The budget required to fund the intervention if all eligible people received the intervention

The method for collecting data to measure the criteria comprised the following steps:

1. Reviews of evidence of effectiveness and cost-effectiveness.
2. Construction of decision models to estimate the cost per QALY gained.
3. Analysis of affordability, reach and inequality score
4. Quality grading of the criteria estimates
