Effects of insulin-induced hypoglycaemia on cardiac function in people with type 1 and type 2 diabetes and people without diabetes.
Article in Diabetes, obesity & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
aimsCardiovascular disease is the most common complication and cause of death in people with diabetes. Hypoglycaemia is independently associated with the development of cardiovascular complications, including death. The aim of this study was to assess changes in cardiac function and workload during acute hypoglycaemia in people with and without diabetes and to explore the role of diabetes type, magnitude of the adrenaline response, and other phenotypic traits. MATERIALS AND
methodWe enrolled people with type 1 diabetes (n = 24), people with insulin-treated type 2 diabetes (n = 15) and controls without diabetes (n = 24). All participants underwent a hyperinsulinaemic-normoglycaemic-(5.3 ± 0.3 mmol/L)-hypoglycaemic (2.8 ± 0.1 mmol/L)-glucose clamp. Cardiac function was assessed by echocardiography, with left ventricular ejection fraction (LVEF) as the primary endpoint.
resultsDuring hypoglycaemia, LVEF increased significantly in all groups compared to baseline (6.2 ± 5.2%, p < 0.05), but the increase was significantly lower in type 1 diabetes compared to controls without diabetes (5.8 ± 3.4% vs. 9.4 ± 5.0%, p = 0.03, 95% CI difference: -5.0, -0.3). In people with type 1 diabetes, ΔLVEF was inversely associated with diabetes duration (β: -0.16, 95% CI: -0.24, -0.53, p = 0.001) and recent exposure to hypoglycaemia (β: -0.30, 95% CI: -0.53, -0.07, p = 0.015). Hypoglycaemia also increased global longitudinal strain (GLS) in controls without diabetes (p < 0.05), but this did not occur in the two diabetes subgroups (p > 0.10).
conclusionsHypoglycaemia increased LVEF in all groups, but the increase diminished with longer disease duration and prior exposure to hypoglycaemia in type 1 diabetes, suggesting adaptation to recurrent hypoglycaemia. The increment in GLS observed in controls was blunted in people with diabetes. More research is needed to determine the clinical relevance of these findings.
