Correlation between stress hyperglycemic ratio and all-cause mortality in diabetic patients with heart failure.
Article in BMC endocrine disorders, 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 stress hyperglycemia ratio (SHR) quantifies the intensity of stress hyperglycemia by highlighting the rate of change in fasting blood glucose during stress. Several studies have validated the association of SHR with poor prognosis in cardiovascular disease. However, the value of SHR in diabetic patients with severe heart failure requiring ICU admission remains unclear. The aim of this study was to investigate the predictive value of SHR for poor prognosis in diabetic patients with heart failure.
methodsThis study was based on the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database and included diabetic patients with a diagnosis of heart failure. The primary outcome event was all-cause mortality. Patients were grouped according to quartiles of SHR, and the association between SHR and all-cause mortality was assessed using restricted cubic spline analysis, survival analysis, and Cox proportional hazards regression analysis.
resultsA total of 1470 patients (55.7% male) were enrolled in this study. In-hospital mortality and intensive care unit (ICU) mortality reached 12.2% and 7.8%, respectively. In-hospital mortality was significantly higher in the highest quartile group of SHR. After correction for confounders, the risk of death was significantly higher in the highest quartile group compared with the lowest quartile group. Restricted cubic spline plot analysis showed a positive linear relationship between SHR and in-hospital and ICU mortality.
conclusionSHR was significantly associated with in-hospital and ICU all-cause mortality in severe patients. This finding suggests that SHR may be useful in identifying diabetic patients with severe heart failure at high risk for all-cause mortality.
