Table 5 Incremental cost effectiveness ratios and cost-effectiveness relative to no intervention for individual participants in a prevention programme

From: Economic evaluation of type 2 diabetes prevention programmes: Markov model of low- and high-intensity lifestyle programmes and metformin in participants with different categories of intermediate hyperglycaemia

Method of identifying participants Intervention Incremental cost effectiveness ratio (ICER) (relative to next best intervention) Cost effectiveness ratio (CER) (relative to no intervention)
Incremental cost (£, 2015) Incremental effect (QALYs) ICER (£/QALY) Probability ICER < £20,000/QALY Cost vs no intervention (£, 2015) Effect vs no intervention (QALYs) CER (£/QALY) Probability CER < £20,000/QALY
