Data-Driven Phenotypic Clusters of Gestational Diabetes Mellitus and Associations With Risk of Perinatal Complications and Postpartum Diabetes.
Article in Diabetes care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveManagement of gestational diabetes mellitus (GDM) largely follows a uniform approach, despite growing recognition of GDM heterogeneity. We aimed to identify data-driven GDM clusters by using machine learning techniques and clinical data and to assess their associations with perinatal complications and postpartum diabetes risk. RESEARCH DESIGN AND
methodsIn a population-based cohort study, 37,544 individuals with GDM were followed up through 12 years postpartum. In the discovery (70%) and validation (30%) sets, we applied dimension reduction and clustering methods using routinely available sociodemographic, behavioral, and clinical variables. Covariate-adjusted modified Poisson and Cox regression models were used to assess associations of GDM clusters with risk of perinatal complications and postpartum diabetes.
resultsFour data-driven GDM phenotypic clusters were identified. Cluster 1 (C1) (65.6%), C2 (14.5%), C3 (12.0%), and C4 (7.8%) comprised the discovery set, with similar distributions in the validation set (C1-C4 66.7%, 14.0%, 12.0%, 7.4%, respectively). C2-C4 compared with C1 (late-diagnosed, lower-BMI, and postload hyperglycemia GDM) were associated with higher risks of perinatal complications and new-onset postpartum diabetes, especially C4 (early-diagnosed, comorbidity-related, and high-glucose challenge test GDM) (adjusted relative risks: severe maternal morbidity 1.43 [95% CI 1.19, 1.72] and neonatal intensive unit admission 1.53 [1.41, 1.66]; adjusted hazard ratio for diabetes 4.32 [95% CI 3.94, 4.73]). Within the largest cluster C1, three subclusters were identified, with differential risks of perinatal complications but not postpartum diabetes.
conclusionsOur study identified distinct data-driven GDM phenotypic clusters with differential risks of perinatal complications and postpartum diabetes. These findings may inform personalized risk assessment and management strategies tailored to GDM phenotypic clusters to possibly reduce adverse health outcomes.
