The additional quality-adjusted life years (QALYs) gained by ILI were not statistically significant, with values of 0.17 and 0.16 measured by SF-6D and Feeling Thermometer, respectively.
The lack of statistically significant QALY gains suggests that intensive lifestyle interventions may not provide additional health benefits over standard education.

- The mean cumulative intervention costs for the intensive lifestyle intervention (ILI) were $11,275 per person, compared to $887 for standard diabetes support and education (DSE), resulting in ILI costing $6,666 more per person than DSE.Strong
- The cost-effectiveness of ILI over the 9-year period is unclear due to different health utility measures leading to different conclusions.Strong
