Association of hyperuricaemia and hyperglycaemia with risk of in-hospital mortality in acute aortic dissection: a multicentre cohort study in the Han Chinese population.
Article in BMJ open, 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
objectiveThe objective is to investigate the association of hyperuricaemia and hyperglycaemia with an increased risk of mortality in acute aortic dissection (AAD).
designRetrospective multicentre cohort study.
settingDe-identified information of patients was collected from electronic medical records between 2010 and 2021 across five hospitals in China.
participantsA total of 2603 AAD patients from 5337 patients who underwent arterial aortic computed tomographic angiography were selected after three rounds of screening.
main outcome measureAll-cause in-hospital mortality.
resultsOf the 2603 patients, 20.3% were women, and the mean age was 54 years old. In-hospital mortality risk escalated linearly with increased levels of uric acid (P non-linearity=0.1699) and serum glucose (P non-linearity=0.2423). The per SD of increment in uric acid was associated with 40% (1.40, 1.22 to 1.60) in HR and 95% CI of AAD all-cause in-hospital mortality and 39% (1.39, 1.22 to 1.58) in serum glucose after full adjustment. Patients with a decrease in uric acid and/or serum glucose within the 7 days preceding admission showed significantly lower in-hospital mortality compared with those without a decrease. Notably, patients exhibiting both hyperuricaemia and serum glucose>180.2 mg/dL faced over double mortality risk (2.21, 1.58 to 3.10) compared with those with normal uric acid and normal serum glucose levels.
conclusionsHyperuricaemia and hyperglycaemia are significantly associated with an increased risk of mortality among AAD patients in the Han Chinese population. These findings suggest the importance of monitoring and managing uric acid and glucose levels in AAD patients to potentially improve outcomes.
