Prediction of phase angle based on body composition: Insights from a large population-based registry.
Article in Journal of education and health promotion, 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
backgroundPhase angle (PhA) is obtained through bioelectrical impedance analysis (BIA) and is a potential marker of nutritional health and cellular function. We aimed to develop an equation for estimating PhA using body composition parameters, focusing on skeletal muscle mass, body water, and fat mass. MATERIALS AND
methodsThis cross-sectional study enrolled participants from the Iranian National Obesity Registry. Data on age, gender, body composition, and BIA measurements were collected using an InBody 770 device. Exclusion criteria included pregnancy, pacemakers, implants, or edema. The study was approved by the Ethics Committee of Mashhad University of Medical Sciences.
resultsA total of 5980 participants (28.7% men, 71.3% women) were included. PhA showed the strongest correlations with extracellular water/total body water (ECW/TBW) (
conclusionECW/TBW, SMM, BFM, age, and height are significant predictors of PhA, with ECW/TBW showing the strongest negative association.
