Effectiveness of behavioural economics-based financial incentives and social feedback on glycaemic control and physical activity in adults with newly diagnosed type 2 diabetes: A randomised control trial.
Trial report in Diabetes, obesity & metabolism, 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
aimsTo assess the effectiveness of behavioural economics-based financial incentive and social comparison feedback in adults with newly diagnosed type 2 diabetes. MATERIALS AND
methodsWe conducted a pragmatic randomised control trial with 6-month intervention and 3-month post-intervention follow-up. Participants were randomised to three groups: financial incentive (FI), financial incentive and social comparison feedback (FS), and control. Intervention groups received loss-framed financial incentives to meet personalised weekly step-count targets, with the FS group additionally receiving peer encouragement. We performed intention-to-treat analysis with multiple imputation and generalised estimating equations (GEE).
resultsAmong 99 adults newly diagnosed with type 2 diabetes, mean HbA1c at baseline in the control, FI, and FS groups were as follows: 52.5 (NSGP: 7%) (SD: 5.4), 52.9 (7%) (4.1), and 54.5 (7.1%) (4.9) mmol/mol. There were no significant decreases in HbA1c, weight, cholesterol or triglycerides in the incentive groups versus control at 6 or 9 months. There were significant increases in step count and physical activity at 6 months compared to control (FI: +1283 steps/day, p < 0.001; FS: +1545 steps/day, p < 0.001; FS group +774 MET-minutes/week, p < 0.001).
conclusionsFinancial incentive and social comparison feedback improved physical activity in people newly diagnosed with type 2 diabetes but were insufficient to achieve a significant improvement in glycaemic control.
