Subphenotyping of prediabetes with a phenotypic tree model and its correlations with outcomes: Insights from two Chinese cohorts.
Article in Journal of translational internal medicine, 2026. 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 Objectives: To investigate whether stratifying participants with prediabetes using the Scottish tree model could identify their risks of developing diabetes and related outcomes. Methods: The current study enrolled subjects with prediabetes at baseline from the China Health and Retirement Longitudinal Study and the Chinese follow-up cohort, comprising 10,165 and 4,090 participants, respectively. We assigned individuals to the Scottish tree using the mapping function based on nine phenotypic variables, including HbA1c, BMI, blood lipids, liver enzyme, creatinine, and blood pressure. Cox proportional hazards regression models were utilized to assess the relationships between dimensions on the tree and future diabetes, renal and cardiovascular diseases, and death from all causes. Results: Our findings showed that individuals in the upper-right branch of the tree exhibited the increased risk of progression to subclinical atherosclerosis, cardiovascular disease, microalbuminuria, and all-cause mortality, potentially linked to elevated blood pressure, dyslipidemia, and body fat percentage. Individuals in the right part of the tree were more likely to progress to the onset of type 2 diabetes and chronic kidney disease, which was possibly associated with insulin resistance, triglycerides, and blood pressure. Conclusions: The phenotypic tree model could be incorporated into future risk stratification and treatment plans to better benefit individuals with prediabetes.
