Association of triglyceride-glucose index with risk of cardiovascular disease among patients with prediabetes: population based prospective cohort study.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 was associated with an increased risk of cardiovascular disease (CVD) in patients with prediabetes. However, this association has not yet been evaluated in prospective studies. Hence, we aimed to investigate the association between the TyG index and the risk of incident CVD in patients with prediabetes.
methodsParticipants with prediabetes were enrolled from the Kailuan study and were followed up for clinical events until 2022. The exposure variable was TyG index. The primary outcomes were the incidence of CVD events, including ischemic heart disease and stroke, while the secondary outcomes were each specific type of CVD events. Cox proportional hazards regression models and restricted cubic spline analysis were used to calculate multivariable-adjusted hazard ratios and investigate exposure-response association, respectively.
resultsOver a mean follow-up period of 14.19 years, 13.81% (n = 2,537) of the 18,364 participants with prediabetes developed CVD events. Compared with participants in the lowest TyG index quartile (Q1, TyG index < 8.45), those in Q2 (TyG index 8.45-8.81), Q3 (TyG index 8.81-9.23), and Q4 (TyG index ≥ 9.23) were associated with an increased risk of CVD, with hazard ratios (HRs) of 1.18 (95% confidence interval [CI] 1.05-1.34), 1.29 (95% CI 1.15-1.46), and 1.45 (95% CI 1.28-1.63), respectively. For each unit increase in TyG index, the risk of CVD events increased by 12% in prediabetes patients. We also found a linear association between baseline TyG index and CVD events in prediabetes patients (P-non-linear = 0.12).
conclusionsTyG index is an independent risk factor for incident CVD in the prediabetes patients.
