Stress hyperglycemia ratio and mortality risk in cardiometabolic multimorbidity: a multicenter retrospective study.

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
aimsThis study aimed to investigate the association between the Stress Hyperglycemia Ratio (SHR) and mortality risk in critically ill patients with cardiometabolic multimorbidity (CMM), and to explore the potential mediating roles of white blood cell count (WBC), albumin, and creatinine.
methodsWe conducted a multicenter retrospective cohort study using data from the MIMIC-IV database (n = 1,214) for derivation and the NWICU database (n = 686) for external validation. The relationship between SHR and all-cause/28-day mortality was analyzed using multivariate logistic regression, restricted cubic splines, and machine learning models. Mediation analysis was performed to assess the roles of WBC, albumin, and creatinine.
resultsA nonlinear relationship with threshold effects was observed between SHR and mortality. In the fully adjusted model, the highest SHR tertile (Q3) was independently associated with increased risks of all-cause mortality (OR = 1.58, 95% CI: 1.13–2.20) and 28-day mortality (OR = 1.98, 95% CI: 1.24–3.18). Random Forest and XGBoost models demonstrated the best predictive performance for 28-day mortality (AUC = 0.765). Calibration curves confirmed the reliability of the risk estimates. Mediation analysis indicated that WBC and creatinine may partially mediated the adverse effects of SHR, while albumin exerted a protective mediating effect.
conclusionsSHR is a significant and independent predictor of mortality in critically ill patients with CMM, exhibiting a nonlinear association. WBC, creatinine, and albumin may partially mediate this relationship, offering insights for future mechanistic studies. However, these findings are specific to the ICU population and warrant further validation in other cohorts.
