Percent body fat misclassifies patients with sarcopenia as obese: support for fat mass index in obesity assessment.
Article in Journal of the Endocrine Society, 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
Background: Percent body fat (%BF) is a common measurement reported on dual-energy X-ray absorptiometry (DXA) to assess for obesity. %BF is calculated as fat mass divided by total body mass, and thereby increases with either higher fat mass or reduced muscle mass. In contrast, fat mass index (FMI; kg/m Methods: We utilized whole-body DXA data from 1999-2006 NHANES in adults ≥20 years of age ( Results: More patients met criteria for obesity when defined by %BF (76.8%) compared to BMI (33.9%), FMI (35.8%), and WC (51%). Participants classified as obese by %BF had lower lean (muscle) mass, FMI, and BMI compared to participants obese by FMI (all Conclusion: Patients who are classified as obese by %BF had the lowest muscle mass and fat mass compared to participants who met other definitions of obesity. The majority of patients with sarcopenia are labeled as obese by %BF. We believe these findings support the use of FMI, a measurement not confounded by muscle mass, for research and clinical assessment.
