Predictive value of GNRI and TyG index for poor prognosis in NSTE-ACS patients post-PCI.
Article in Asia Pacific journal of clinical nutrition, 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
BACKGROUND AND
objectivesThis study aimed to assess the predictive power of the Geriatric Nutritional Risk Index (GNRI) and the triglyceride-glucose (TyG) index for poor prognosis in non-ST segment elevation acute coronary syndrome (NSTE-ACS) patients post-percutaneous coronary intervention (PCI). METHODS AND STUDY
designA cohort of 393 NSTE-ACS patients who underwent PCI at the People's Hospital of Nanjing Jiangbei from 2016 to 2022 was analyzed. Major adverse cardiovascular events (MACEs), including death, non-fatal myocardial infarction, and target vessel revascularization, served as the primary outcome. Relationships between GNRI, TyG index, and MACEs were explored using univariate and multivariate logistic regres-sion, with results presented as odds ratios (OR) and 95% confidence intervals (CI). The predictive value was further evaluated using the area under the curve (AUC) from the receiver operating characteristic (ROC) curve.
resultsMACEs occurred in 34 patients. A TyG index ≥1.36 was associated with a significantly increased risk of MACEs (OR=5.07, 95%CI: 1.64-15.71), while a GNRI ≥108 indicated a decreased risk (OR=0.17, 95%CI: 0.04-0.68). These associations were consistent across various subgroups, including age, gender, and specific pre-existing conditions. The combined predictive value of TyG index and GNRI was higher than each alone (AUC=0.711, 95%CI: 0.642-0.779).
conclusionsIn post-PCI patients with NSTE-ACS, the TyG index and GNRI are significant predictors of MACEs, with the TyG index indicating higher risk and GNRI lower risk. Their combined use may enhance the predictive accuracy for MACEs in this patient population.
