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
aimsOne-hour postload plasma glucose (1h-PG) is an early marker of dysglycemia in adults, but its utility in children and adolescents is uncertain because insulin sensitivity changes during growth and puberty. We aimed to establish age- and pubertal stage-specific 1h-PG thresholds for identifying prediabetes and Type 2 diabetes (T2D) in children with overweight or obesity. MATERIALS AND
methodsIn this cross-sectional study, 4344 children and adolescents with overweight or obesity underwent an oral glucose tolerance test. Participants were classified into four groups: normal glucose tolerance (NGT) with normal 1 h-PG, NGT with elevated 1 h-PG, prediabetes and T2D. Insulin resistance and β-cell function indices were assessed. Participants were stratified by chronological age and pubertal stage. The optimal 1h-PG cut-offs were obtained via receiver operating characteristic (ROC) and age- and pubertal stage-based thresholds were compared for diagnostic performance. These thresholds were then validated in two independent cohorts.
resultsAmong individuals with NGT, those with elevated 1h-PG exhibited greater insulin resistance, impaired β-cell function and a higher insulin area under the curve (29 916 vs. 23 524, p < 0.001). 1 h-PG levels increased with pubertal progression. Pubertal stage-specific thresholds showed superior discrimination compared with age-based stratification and adult cut-offs. Compared with adult thresholds (8.6 mmol/L for prediabetes and 11.6 mmol/L for T2D), a prepubertal cut-off of 7.78 mmol/L improved sensitivity for prediabetes (75.40% vs. 56.68%) and a pubertal cut-off of 10.48 mmol/L improved sensitivity for T2D (89.47% vs. 73.68%).
conclusionsElevated 1h-PG proved to be a practical marker for identifying early metabolic dysfunction in children and adolescents with euglycemia. Given that widely used adult-derived cut-offs (8.6 and 11.6 mmol/L) are suboptimal for pediatric populations, we established pubertal stage-specific thresholds that outperformed both age-specific and adult-derived cut-offs. These stage-specific thresholds may serve as an effective screening tool for diabetes risk in children and adolescents with overweight or obesity.
