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
aimsPrognostic markers for microvascular complications in type 1 diabetes are needed because factors beyond hyperglycaemia contribute to this risk. The triglyceride-glucose (TyG) index is an established marker of vascular complications in type 2 diabetes; however, its clinical significance in type 1 diabetes remains unknown. We aimed to investigate the association between the TyG index and long-term renal outcomes in a nationwide cohort of adults with type 1 diabetes. MATERIALS AND
methodsIn this nationwide cohort study of 14 782 adults with type 1 diabetes from the Korean National Health Insurance Service database, we used Cox proportional hazards models to evaluate the risk of incident chronic kidney disease (CKD) and end-stage renal disease (ESRD) across quartiles of the baseline TyG index during a median follow-up of 7.04 years.
resultsA significant dose-response relationship was observed between the TyG index and adverse renal outcomes. After multivariable adjustment, the highest TyG quartile (Q4) had a 2.15-fold (95% confidence interval, 1.87-2.48) and a 2.90-fold (95% confidence interval, 2.25-3.75) higher risk of developing CKD and ESRD, respectively, than the lowest quartile (Q1) (p for trend <0.001 for both). These associations remained significant in a competing-risk analysis that included all-cause mortality. Additionally, higher TyG quartiles were associated with a progressively worsening distribution of 5-year CKD stages.
conclusionsThe TyG index may serve as a valuable clinical indicator to identify individuals with type 1 diabetes at high risk for developing incident CKD and ESRD.
