Neck circumference is associated with metabolic syndrome parameters in adolescents with obesity: a cross-sectional study.
Article in BMC pediatrics, 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
backgroundNeck circumference (NC) is a practical anthropometric measure for assessing obesity in youth, but its association with metabolic syndrome (MetS) components remains underexplored. This study evaluated the relationship between NC and MetS parameters in adolescents with obesity, using both standard International Diabetes Federation (IDF) criteria and expanded definitions incorporating insulin resistance.
methodsIn this cross-sectional study, 48 adolescents with obesity and 41 age- and sex-matched controls were recruited from a tertiary pediatric clinic. Anthropometric data (BMI, waist circumference, NC) and fasting blood samples (glucose, insulin, HDL cholesterol, triglycerides) were collected. MetS was diagnosed using IDF criteria and an expanded definition including hyperinsulinemia or elevated HOMA-IR. The Pediatric siMS (PsiMS) score quantified metabolic risk.
resultsNC was significantly greater in the obesity group than in controls (mean ± SD: 37.95 ± 3.03 cm vs. 31.86 ± 3.30 cm, p < .001). MetS prevalence was 14.6% by IDF criteria, rising to 43.8% with expanded criteria. In adolescents with obesity, NC positively correlated with fasting insulin, HOMA-IR, triglycerides, systolic blood pressure, and PsiMS score (p < .05 for all). NC was also associated with the total number of MetS criteria met under both diagnostic approaches.
conclusionsNC is a reliable, non-invasive marker correlated with key metabolic risk factors in adolescents with obesity. Its routine use could aid early detection of metabolic risk, particularly in resource-limited settings. Longitudinal research is needed to define NC thresholds and its predictive value for long-term outcomes.
