Developmental stages and exercise timing in relation to fear of hypoglycemia and quality of life in type 1 diabetes.
Article in Endocrine, 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
purposeTo examine associations between physical activity (PA) characteristics and psychosocial outcomes - quality of life (QoL) and fear of hypoglycemia (FH) - in children, adolescents, and young adults with type 1 diabetes (T1D).
methodsIn this cross-sectional study, 100 insulin pump-treated outpatients T1D completed 7-day PA logs capturing timing, type, intensity, and volume. QoL and FH were assessed using age-appropriate validated instruments. General linear models evaluated associations between PA characteristics and psychosocial outcomes, accounting for age group and, in sensitivity analyses, sex and HbA1c.
resultsIn pooled analyses (N = 82 complete cases), age group was significantly associated with both QoL (p = 0.037) and FH (p < 0.001), with a large effect size observed for FH. In sensitivity analyses adjusting for sex and HbA1c, the age-group effect on FH remained robust, whereas associations with QoL were attenuated. Exercise timing was associated with FH (p = 0.047), with higher adjusted FH scores observed among individuals reporting evening exercise. However, pairwise comparisons were not significant after correction. No significant AgeGroup×Timing interactions were detected. Preferred exercise type and intensity were not independently associated with psychosocial outcomes. In sensitivity analyses adjusted for sex and HbA1c (N = 62), the age-group effect on FH remained robust, whereas timing showed borderline significance.
conclusionDevelopmental stage appears to be a major determinant of fear of hypoglycemia in youths with T1D. Exercise timing may contribute modestly to perceived hypoglycemia risk, particularly for evening activity, although findings were attenuated after adjustment. These cross-sectional associations highlight the importance of developmentally tailored exercise counselling, while longitudinal studies are needed to clarify directionality.
