Does Digital Make a Difference? Willingness-to-Pay for Digital Versus Offline Weight Loss in Germany.
Article in Obesity science & practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Germany introduced both digital health applications (DiGA) and an "offline" structured disease management program (DMP) for obesity within statutory health insurance. Given limited resources and ongoing reimbursement decisions, evidence on how individuals with obesity assessed the value of intervention delivery in terms of their willingness to pay (WTP) remained limited. Objective: This study assessed the WTP of individuals with obesity (BMI ≥ 30 kg/m Methods: An online contingent valuation survey was conducted among 424 participants with a BMI ≥ 30 kg/m Results: The mean WTP for the DiGA was €16.15 per month (95% CI: €14.22-€18.09) and was significantly positively associated with older age (€0.24 higher per year, Conclusion: Respondents showed a positive WTP for weight loss interventions, yet at an amount far below DiGA manufacturer prices of approximately €70 per month. The small difference between digital and offline formats suggested that the perceived effectiveness of the intervention had a greater influence on WTP than the format.
