1 · What the graph read from it

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.

2 · The registry

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

Objective: Despite triglyceride glucose-body mass index (TyG-BMI) being a validated marker of insulin resistance, its prospective association with diabetes risk remains unclear; we therefore examined the impact of TyG-BMI on incident diabetes. Methods: This was a retrospective cohort study based on 48,288 adults without diabetes at baseline, identified from a publicly available dataset on the DRYAD platform originally derived from 11 cities and 32 locations in China.Using Cox proportional risk regression modeling combined with cubic spline functions and smoothed curve fitting, we assessed the relationship between the baseline TyG-BMI and the risk of developing DM and explored its nonlinear association. We performed subgroup analyses to assess the consistency of the association across different subgroups. Results: Among 48,288 initially diabetes mellitus (DM)-free participants, 1,230 (2.54%) developed diabetes at follow-up.Adjusted for covariates, TyG-BMI levels(per 10-unit) were positively associated with the risk of diabetes onset (HR = 1.25,95% CI: 1.20-1.29, Conclusion: In Chinese adults, TyG-BMI exhibits a threshold effect on incident diabetes. Individuals above the threshold have a significantly increased risk of developing diabetes. However, the identified threshold (163.38) requires prospective validation in contemporary cohorts. If validated, it may help identify high-risk individuals for targeted prevention in the future.
