Association between the triglyceride-glucose index and severe left main and/or three-vessel disease in patients with non-ST-segment elevation myocardial infarction: a dual-centre 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
objectiveThis study aimed to investigate the relationship between the triglyceride-glucose (TyG) index and the presence of severe left main and/or three-vessel disease (LM/3VD) evaluated by SYNTAX score.
designCross-sectional study.
settingShenzhen Nanshan People's Hospital and The First Affiliated Hospital of Jinan University.
participants596 patients were first diagnosed with non-ST-segment elevation myocardial infarction (NSTEMI). PRIMARY OUTCOME MEASURES: Incidence of severe LM/3VD and the relations between the TyG index and the severe LM/3VD evaluated by SYNTAX score.
resultsAfter fully adjusting for confounders, the TyG index was a significant independent predictor for severe coronary artery disease (CAD) (OR 1.744; 95% CI 1.166 to 2.609; p 0.007). The TyG and severe CAD were found to be linearly correlated using the restricted cubic splines (p for non-linearity=0.161). The TyG demonstrated a consistent association with severe CAD across different subgroups, such as individuals with and without diabetes, hypertension, hyperlipidaemia and different haemoglobin (<6.5 or ≥6.5). No statistically significant interaction was detected within the subgroup (p > 0.05). In comparison to risk factors based solely on age or ST-elevation in lead Augmented Unipolar Right-arm (aVR), the area under the curve value for the prediction of severe CAD was modestly improved to 0.759 by the addition of the TyG.
conclusionPatients with NSTEMI demonstrated that a positive relationship was found between a higher level of TyG and an increased level of coronary anatomical complexity (LM/3VD with SYNTAX score >22). The TyG could serve as a non-invasive marker for predicting severe CAD and have implications for guiding treatment strategies in patients with NSTEMI.
