Type 2 Diabetes Genetic Risk and Type 1 Diabetes Heterogeneity and Progression.
Article in Diabetes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Insulin secretion varies widely in preclinical type 1 diabetes. To understand the pathogenesis of this metabolic heterogeneity, we asked whether genetic predisposition to type 2 diabetes, quantified by a type 2 diabetes genetic risk score (T2D-GRS), modulates β-cell function and disease progression in individuals at risk of type 1 diabetes. We analyzed 4,324 islet autoantibody–positive TrialNet Pathway to Prevention participants with genome-wide genotyping and oral glucose tolerance testing. Both T2D-GRS and the type 1 diabetes genetic risk score 2 (T1D-GRS2) differed significantly across five previously described groups defined by C-peptide area under the curve (AUC; a measure of insulin secretion). The highest C-peptide AUC group, compared with the lowest, had significantly higher T2D-GRS, lower T1D-GRS2, higher BMI z-score, greater insulin resistance, older age, and lower prevalence of male participants; multiple islet autoantibody positivity; and IA-2 or insulin autoantibody positivity. Progression to clinical (stage 3) type 1 diabetes was significantly associated with T1D-GRS2 across all groups and with T2D-GRS in all but the lowest C-peptide AUC group. In conclusion, type 2 diabetes genetic burden shapes metabolic heterogeneity and accelerates progression in preclinical type 1 diabetes. These results support the evaluation of type 2 diabetes–related mechanisms as targets to improve the prediction and prevention of type 1 diabetes. ARTICLE HIGHLIGHTS: Heterogeneity in β-cell function is a barrier to precision medicine in type 1 diabetes. We asked whether type 2 diabetes-associated genes influence insulin secretion and progression to clinical type 1 diabetes in autoantibody-positive individuals. A type 2 diabetes genetic risk score was associated with higher C-peptide area under the curve (AUC) and increased clinical type 1 diabetes risk in all but the lowest C-peptide AUC subgroup. Addressing type 2 diabetes mechanisms could improve type 1 diabetes prediction and prevention.
