1 · What the graph read from it

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.

2 · The registry

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

Hemorrhagic stroke (HS) is a severe condition with high mortality. Identifying high-risk patients for early intervention remains challenging. The triglyceride-glucose-body mass index (TyG-BMI), a simple and cost-effective marker of metabolic dysfunction, has shown potential as a predictor of all-cause mortality (ACM) in critically ill HS patients. This study aims to evaluate TyG-BMI's role in predicting mortality and its clinical utility in risk stratification. This retrospective cohort study analyzed critically ill hemorrhagic stroke patients in the MIMIC-IV database. Kaplan-Meier curves assessed ACM across TyG-BMI groups, and Cox regression models explored the association between TyG-BMI and ACM. Restricted cubic spline (RCS) analysis identified nonlinear relationships, and subgroup analyses examined variations across clinical populations. A total of 1,121 patients with hemorrhagic stroke were included in the final analysis. Multivariable Cox regression demonstrated that patients in the highest TyG-BMI quartile had significantly elevated all-cause mortality risk compared to those in the lowest quartile after full adjustment for clinical confounders (HR 1.891, 95% CI 1.24-2.89; P = 0.003). RCS analysis revealed a predominantly linear association between TyG-BMI and mortality (P for nonlinearity > 0.05). Using a clinically relevant threshold of 211.32 (corresponding to the cohort median), patients with TyG-BMI ≥ 211.32 exhibited 1.82-fold higher mortality risk (95% CI: 1.45-2.28; P < 0.001) compared to those below this threshold. The addition of TyG-BMI to the APACHE-IV scoring system significantly improved predictive accuracy for in-hospital mortality (ΔAUC = 0.118, 95% CI 0.053-0.183; P = 0.002). This study demonstrates that TyG-BMI is an independent risk factor for ACM in critically ill HS patients, providing strong evidence to support its use as a reliable biomarker for identifying high-risk patients with elevated mortality.
