Assessing the Diagnostic Performance of Triglyceride-Glucose-Based Indices for Early Detection of Metabolic Syndrome in Paediatric Down Syndrome.
Article in Journal of intellectual disability research : JIDR, 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
backgroundDown syndrome (DS) youth have an increased risk of metabolic syndrome (MetS). This study assessed the diagnostic performance of the triglyceride-glucose index (TyG) and its derivatives-TyG-BMI, TyG-waist circumference (WC) and TyG-waist-to-height ratio (WHtR) in detecting MetS compared with traditional markers.
methodsWe retrospectively analysed data from 60 DS patients and 40 controls; IR was estimated using HOMA-IR, TyG, TyG-BMI, TyG-WC and TyG-WHtR indices. MetS was defined by the presence of at least three of the following criteria: BMI z-score ≥ 2 SD and/or WC/H ratio ≥ 0.5; fasting glucose > 100 mg/dL and/or pathological HOMA-IR; dyslipidaemia; hypertension.
resultsMetS prevalence was 15% in DS. HOMA-IR showed the highest sensitivity (0.667) and specificity (0.80) to detect MetS, while TyG demonstrated similar performance (sensitivity 0.667; specificity 0.843) and the best overall accuracy (0.817). Composite indices showed moderate accuracy but high specificity.
conclusionsTyG, being simple and cost-effective, may be a valuable alternative for early MetS detection in DS.
