Numeracy Skills and Glycemic Control in an Observational, Multicenter, Cross-Sectional, and International Study of Children with Type 1 Diabetes.
Observational study in Hormone research in paediatrics, 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
aimsThis study examined the possible association between numeracy skills and glycemic outcomes in children with type 1 diabetes.
methodsThe study used a cross-sectional design and collected data from 7 centers of the Hvidoere Study Group. HbA1c was measured centrally. Numeracy was assessed using the specific 5-item Diabetes Numeracy Test (DNT-5) and the international, general Wordless Mathematical Test (WMT). The HbA1c predictive multivariate generalized linear model was constructed using the adjusted R-squared index for model selection. Pearson's correlation coefficient was calculated between observed and predicted HbA1c levels in the training and testing datasets.
resultsOverall, 306 adolescents aged 12-18 (mean age 14.96 ± 1.68) years and diabetes duration of 6.57 (±3.75) participated in this study. Numeracy skills, as assessed by the WMT but not DNT-5, predicted the HbA1c levels after adjustment for sociodemographic and clinical factors. The correlation between observed and predicted HbA1c levels was consistent in both datasets and was 0.34 (N = 155) and 0.37 (N = 61) for the training and test datasets, respectively (p = 0.412). The effect size for the WMT-based predictive model of HbA1c adjusted for clinical and socioeconomic factors was significantly higher (p < 0.05) than the single-parameter-based model.
conclusionsNumeracy, as assessed by an international general math test, is a good predictor of HbA1c in children and adolescents with type 1 diabetes. The basic and short WMT is a potentially effective tool in personalized clinical pediatric diabetes practice. Therapy planning should consider adjusting therapy to compensate for lower numeracy skills and/or training to improve the patient's numerical proficiency.
