Cost-effectiveness of goal-directed and outcome-based financial incentives for weight loss in low-income populations: the FIReWoRk randomized clinical trial
Authors' conclusion
Goal-directed and outcome-based financial incentives were cost-effective strategies for helping low-income individuals with obesity lose weight. Their incremental cost per kilogram lost were comparable to other weight loss interventions.
