Associations of Metabolic Phenotypes with Cardiac Structure and Clinical Outcomes: Insights from the UK Biobank.
Article in The Journal of clinical endocrinology and metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
contextMetabolic syndrome and obesity represent major cardiovascular risk factors, yet their combined effects on cardiac structure and clinical outcomes remain incompletely understood.
objectiveTo examine associations between metabolic phenotypes, cardiac magnetic resonance imaging (CMR), and clinical outcomes.
designProspective study with a median 5.1-year follow-up.
settingPopulation-based cohort from the UK Biobank.
participantsA total of 22 789 participants (mean age 64.1 ± 7.5 years, 52.6% female) were categorized as metabolically healthy nonobese (MHN) vs obese (MHO) or unhealthy nonobese (MUN) vs obese (MUO), based on obesity (body mass index ≥30 kg/m²) and metabolic status (prevalent diabetes or both hypertension and hyperlipidemia). MAIN OUTCOME MEASURE(S): Primary and secondary endpoints were major adverse cardiovascular events (MACE) and all-cause mortality, respectively. CMR included left ventricular ejection fraction (LVEF, %), end-diastolic volume (LVEDV, mL), myocardial mass (g), wall thickness (mm), cardiac output (L/min), and left atrial volume (mL). Linear regression and Cox proportional hazards models, adjusted for age, sex, and smoking, assessed associations between metabolic phenotypes, CMR, and clinical outcomes.
resultsIn adjusted models, all phenotypes demonstrated increased WT (MHO: β=.53 [.50, .55]; MUN: β=.24 [.21, .27]; MUO: β=.66 [.61, .70]), compared to MHN. LVEDV was increased in obesity phenotypes (MHO: β=4.67 [4.07, 5.27]; MUO: β=5.14 [4.05, 6.22]) and decreased in MUN (β=-1.25 [-1.95, -.55]), while MUO showed reduced LVEF (β=-.48 [-.91, -.04]). MACE risk was increased in unhealthy phenotypes (MUN: adjusted hazard ratio (aHR) = 1.55 [1.16-2.07]; MUO: aHR = 1.95 [1.28-2.97]). All phenotypes showed increased all-cause mortality risk (MHO: aHR = 1.65 [1.23-2.21]; MUN: aHR = 1.41 [1.05-1.90]; MUO: 2.10 [1.41-3.15]).
conclusionMetabolic phenotypes show distinct cardiac structural changes and increased mortality risk, supporting their potential in cardiovascular risk stratification.
