Impact of Blood Pressure on Sudden Cardiac Arrest in Diabetic Patients.
Article in Diabetes & metabolism journal, 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
backgruoundHypertension and diabetes mellitus (DM), including pre-hypertension and impaired fasting glucose (IFG), are associated with increased risk of sudden cardiac arrest (SCA). However, interaction between hypertension and DM needs further examination.
methodsThis study utilized data from the South Korean national healthcare insurance system. People who underwent nationwide health screening in 2012 were enrolled. The impact of blood pressure on SCA was evaluated in both diabetic and non-diabetic patients.
resultsA total of 4,593,706 people were analyzed with 3,097,423, 1,034,563, and 461,720 people included in non-DM, IFG, and DM group, respectively. Both high blood pressure (systolic, diastolic, and pulse) and DM were associated with an increased risk of SCA with the highest absolute risk observed in patients with both conditions. A significant interaction was found between blood pressure and DM (P for interaction <0.01): the relative influence of blood pressure on SCA risk was greater in the non-diabetic population. Importantly, in diabetic patients, a J-shaped association was observed; not only high but also low systolic blood pressure (<100 mm Hg) was associated with a significantly increased risk of SCA.
conclusionAlthough the risk of SCA was highest in people with both hypertension and DM, the degree of association between blood pressure and SCA was more pronounced in non-diabetic people. In patients with diabetes, both high and low systolic blood pressure are associated with an elevated risk of SCA. While controlling hypertension is crucial for all individuals, avoiding hypotension may be another important strategy for preventing SCA in people with diabetes or individuals with diabetes.
