Triglyceride-glucose index correlates with all-cause mortality of patients in intensive cardiac care unit: from two large-scale cohorts.
Article in International journal of surgery (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe triglyceride-glucose (TyG) index is widely recognized owing to its effectiveness and practicality in evaluating insulin resistance and has been confirmed to correlate with adverse outcomes in multiple cardiovascular diseases. The current study intends to clarify the relationship between the TyG index and clinical prognoses among populations in the intensive cardiac care unit (ICCU).
methodsThis multicenter, retrospective investigation leveraged records from 209 medical centers. Kaplan-Meier curves were employed to assess the cumulative incidence of mortality. The association between TyG index and prognostic outcomes in the ICCU patient cohort was evaluated using Cox and linear regression analyses, along with restricted cubic splines (RCS). Correlation analysis was conducted to examine the link of TyG with cardiovascular risk factors. To mitigate potential confounding influences, we applied propensity score matching (PSM), overlap weighting (OW), and inverse probability of treatment weighting (IPTW) methodologies. Subgroup analyses were carried out according to identified modifiers.
resultsTotally, 4508 individuals admitted to the ICCUs were ultimately enrolled. Dual in-hospital and intensive care unit (ICU) mortality exhibited gradual increases following higher TyG quartiles (all log-rank P for trend <0.001). Multivariate cox regressions revealed significant correlations of TyG with both in-hospital [adjusted hazard ratio (HR): 1.789] and ICU mortality (adjusted HR: 1.908). RCS analysis revealed linear correlations of elevated TyG with increased mortality risk. An elevated risk of mortality was evident among cohorts following PSM, OW, or IPTW adjustments with higher TyG index. Significant correlations between TyG and certain cardiovascular risk parameters were observed, while no significant correlation was found with length of stay. Subgroup analyses identified a strong link of the TyG with mortality among males, elderly individuals, and those without DM, as well as a notable trend in cardiac surgery/cardiothoracic intensive care units.
conclusionsElevated TyG index was found to significantly correlate with increased mortality risks in patients admitted to the ICCUs, providing new perspectives on the importance of TyG in severe cardiovascular illnesses.
