Results of cost-effectiveness analysis and sensitivity analysis time horizon 10 years: After minus before.

Total cost, deaths and QALYs calculated over 6438 patients. All costs in 2010/11 UK£ (key figures in US$ in text). In the 10 year model costs and benefits are discounted at an annual rate of 3.5%. In the difference (“Diff.”) columns negative (positive) costs, deaths and QALYs mean that costs, deaths and QALYs are lower (higher) in the After period compared with the Before period. “Dominant” means that costs are lower and either deaths are lower or QALYs are higher in the After period compared with the Before period.
