Association between body composition phenotypes and cardiovascular outcomes in patients with coronary artery disease: a retrospective cohort study.
Article in European journal of clinical nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
The prognostic value of body composition phenotypes in coronary artery disease (CAD) remains underexplored. We retrospectively analyzed 178 CAD inpatients who underwent bioelectrical impedance analysis (InBody 770). K-means clustering using skeletal muscle index (SMI) and body fat percentage (PBF) as primary discriminators identified three phenotypes: Sarcopenic (lowest SMI, ~5.3 kg/m²), Robust (highest SMI, ~7.6 kg/m²), and Sarcopenic-Obesity (low SMI ~ 5.8 kg/m² and high PBF ~ 36.9%). Multivariate logistic regression assessed their associations with cardiovascular outcomes. The Sarcopenic-Obesity phenotype showed the highest prevalence of arrhythmias (39.6%) and heart failure (62.5%) and was independently associated with arrhythmias (OR 2.58, 95% CI 1.17-5.87) and heart failure (OR 2.42, 95% CI 1.18-5.21). Phase angle inversely correlated with ECW/TBW (r = -0.83, p < 0.001) and discriminated heart failure (AUC = 0.72). Body composition phenotyping, especially sarcopenic obesity, identifies high-risk CAD inpatients beyond traditional factors.
