Effect of dapagliflozin on blood and breath ketones during supervised insulin withdrawal in adults with type 1 diabetes: A randomized crossover trial.
Trial report in Diabetes, obesity & metabolism, 2025. 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
aimsSodium-glucose cotransporter 2 (SGLT2) inhibitors increase ketoacidosis risk, limiting their use in type 1 diabetes. To better understand the pathophysiology of SGLT2 inhibitor-mediated ketoacidosis, we measured blood glucose, capillary blood and plasma β-hydroxybutyrate (BOHB) and breath acetone (BrACE) during supervised insulin withdrawal in adults with type 1 diabetes with and without dapagliflozin treatment. MATERIALS AND
methodsTwenty adults with type 1 diabetes underwent supervised insulin withdrawal twice in a randomized crossover design: during usual care and after treatment with dapagliflozin (10 mg daily for 2 weeks plus the test day). After insulin withdrawal, capillary blood glucose, BOHB and BrACE measurements were obtained at least hourly until stopping rules were met (>8 h elapsed, symptoms of ketosis, glucose >400 mg/dL, BOHB >4 mmol/L or participant request).
resultsThe peak BOHB and BrACE values achieved during supervised insulin withdrawal were both greater with dapagliflozin than with usual care. Throughout the insulin withdrawal study, dapagliflozin treatment was associated with significantly greater BOHB and BrACE concentrations. The proportions of participants reaching BOHB >1.5 mmol/L and >2.5 mmol/L during supervised insulin withdrawal were greater in the dapagliflozin arm. Blood glucose reached a lower peak in the dapagliflozin arm.
conclusionsIn adults with type 1 diabetes undergoing supervised insulin withdrawal, dapagliflozin treatment compared to usual care was associated with greater blood and breath ketone concentrations in the absence of significant hyperglycaemia.
