1 · What the graph read from it

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.

2 · The registry

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

aimsTo investigate the relationship between body adiposity and glycemic control in children and adolescents with type 1 diabetes (T1D).

methodsThis cross-sectional study included 364 children and adolescents aged 6-18 years with T1D. Anthropometric indices [BMI, BMI Z-score, waist-to-height ratio (WHtR)] and body composition [fat mass (FM), FM%, fat mass index (FMI)], assessed using bioelectrical impedance analysis, were obtained. Hemoglobin A1c and glucose sensor metrics, including time in range (TIR), were used to assess glycemic control. Associations between variables were analyzed using Spearman's correlation. Logistic regression models were run to identify independent predictors of HbA1c < 7.0% and TIR > 70%, with FMI, WHtR, total daily insulin dose per kg (TDD), treatment modalities, sex, age, diabetes duration, and pubertal stage as independent variables.

resultsAdiposity measures (FMI, FM%, and WHtR) were positively associated with HbA1c and negatively with TIR in both sexes. Logistic regression showed that HbA1c < 7% and TIR > 70% were significantly predicted by FMI [OR(95%CI): 0.822(0.704-0.960), p = 0.013, and 0.807(0.681-0.955), p = 0.012, respectively] and WHtR(x100) [OR(95%CI): 0.927(0.874-0.983), p = 0.013, and 0.923(0.866-0.985), p = 0.015, respectively], independently of TDD, sex, treatment modalities and the other independent variables.

conclusionsBody adiposity negatively impacts glycemic control in children and adolescents with T1D, independent of sex and insulin treatment modalities. Despite technological advances in diabetes care, excess adiposity is emerging as a key modifiable factor associated with poorer glycemic outcomes and, consequently, poorer long-term health in children and adolescents with T1D.
